This is 100% true, and I'll add that another way to cheat the test is to pull the filament extremely tight. It should be pulled just tight enough to take out any slack. Or of course you can use the pre-strung blanks, but those will read about 20% lower than the reel-type holder. I still find the BESS tester to be an invaluable tool for improving and checking on MY sharpening, which is the reason to have one (not to show off).
@@JREwing-se2wk The instructions say essentially what I said above: "The goal here is to simply pull the test media across the gap in the fixture with no slack (slight tension) in the test media. Do not over tension the test media." Tension doesn't have the same impact as speed, so it's not super critical. The difference between correct tension and overtightening is only about 15g. If you do the test the right way the results are very repeatable. I have the PT50B machine which reads to the nearest 5g, and I'd say that's about what the margin of error is for this system. That's why I chose the somewhat cheaper PT50B over the PT50A which reads to the nearest 1g.
@@littlejackalo5326 I agree that the test clips would be best for comparing results on UA-cam. But this is what Edge on Up says about them: "While test clips utilize the same test media that is found in our TM02 test media canisters, DTC100 test clips are not BESS CERTIFIED and are useful for highly repeatible relative edge measurements only. Test clip measurements yield approximately 80% of the force required when using our BESS CERTIFIED ATF10G fixture."
You can buy the protest strips if you want consistency Or. You can get a magnetic clip and use a specific weight (ie: 100 grams) to pull the wire taught each time so you can at least create your own consistency as best as possible
I use weights to ensure BESS C media is always at same tension. I also go slow as per instructions. I have seen too many fake ones done on UA-cam where I can tell they are going too fast. I am glad you demonstrated how results can be manipulated.
Great vid Jerad, bringing light to an issue that's becoming more prevalent with these Bess Testers. Would be great to see a mechanical arm that clamps onto the knife and would apply constant pressure until the wire breaks, take the human part out of the equation all together. Thanks for the great vid and keep making sharp things fun and enjoyable
Glad you brought this subject back to the foreground! Haven't seen anyone discuss this since Frankie and Bird were presenting their new tester and showing off the edge that Bird put onto a knife with his KME sharpener. He was getting wicked readings in the low double digits.... and they were using the tester properly!
Thanks for showing us the limitations of the tool. I would say, though, that the tool doesn’t lie… instructions are to be followed and the tool should be respected. There’s nothing inherently wrong with the tool… people just aren’t honest with how they use it. It’s like how I teach student about statistics. Statistics don’t lie - people do. People can frame true statistics in such a way that give a very biased picture. Just like with this tool.
Great video man!! I've seen those crazy low BESS scores and have really wondered what was going on. I own a BESS tester and always do three cut averages when I'm serious about it. IMO you have to question your own results when doing any kind of testing. It's very easy to fool yourself when you're motivated by the feedback.
CAPS LOCK is a button on a computer keyboard that causes all letters of Latin and Cyrillic based scripts to be generated in capital letters. It is a toggle key: each press reverses the previous action.
It feels disingenuous for you to title this why this tester shouldn't be trusted, when the tester in fact does work as advertised when it's used within recommended parameters. It's the people using it wrong that causes the results to be skewed. Use anything wrong and your results won't come out correct.
I’ve been sharpening for my job since the 90’s and have had the PT50A model for 6-7 years now. I would love to see everyone start calling out these people en masse as the disinformation is not only obnoxious but likely discourages others starting out when they try to copy what they see with underwealming results. I’ve seen so many fail to use the tester properly and have a hard time believing it’s ever from a lack of knowledge on using the tester correctly as even the owner has an instructional video here. I believe people are doing it for some false ego boost or more nefariously to dupe viewers that don’t know better to overhype sharpening products they are selling/affiliated with. IDK why so people feel qualified to teach others skills they’re still just learning themselves, but UA-cam is flooded with self proclaimed “experts” who never have sharpening stones with any wear to them. The BESS Tester is great for confirming an edge is not passing other tests (ie push cut accross grain of thin rolling papers or HHT) from simply a weak but polished burr as it will just mushroom on the test media.
This is the test that the tumbler diamond rolling knife sharpener has been using for their ads. I knew it was too good to be true. Thanks for making this video. 😁👍
Excellent video man. Honest approach. I had no idea it could be manipulated so much by speed. It also has issues when comparing cutting capacity of polished edge vs aggressive edge. A polished edge sometimes will stop cutting rope at 300 BESS while an aggressive edge sometimes keep cutting up to 500. I think that makes sense even without any manipulation. BESS will measure keenness but, since there is no slicing motion, it doesn't take in account how serrated the edge is.
It would be fascinating to see results on something like dendritic cobalt. That stuff cuts like crazy, but is probably not going to test well on the BESS
Thanks for this eye opening review. I see many reviewers just barrel through the wire. I’m sure most aren’t trying to get one over on me, so I hope this makes its way to all. ❤❤
Another great video, I have one that I use and can regularly get an edge in 130-180 if working with good steels that have been heat treated properly. I just thought I must not be very good at it after watching some videos. Thx for pointing out that cheating is possible. Should have known
I never realized it was a *wire* being cut. For some reason, I thought it was a little clear plastic card being cut into. Since it's a wire, is BESS basically testing micro bevel acuity, independent of overall edge geometry?
If you use it properly, then why should you not trust it? The video should probably be called "Why you should not trust the Testers on the internet using this tester". The title disparages a tool that a lot of people use successfully and consistently with proven results. This is my first experience with clickbait on your channel.
The title is wrong... They all work the same way. You have to use this tool the correct way, just like with any other tool. I made my own that works great, but still it will read false if I cut the wire too fast. You make it sound as though this scale is a waste of money, it is not. I made my own because I can't afford this one, but again - they ALL work the same, you just have to use it correctly - that is what your title should have stated...
Completely agree! Very similar any other way a person might “test” the capabilities of the knife; a tool can be used correctly or incorrectly changing the type of any results seen.
@@nateubl7235 Exactly... If you bring your knife down too fast, it will say the knife is way sharper than it really is (and some use that technique to falsify how sharp their knives they are selling are unfortunately), but if you bring the blade down slowly (like your supposed to do), you get a much much better accuracy on sharpness. It would be great if they could come up with an adapter that would only let the blade lower at a specific speed, making it even more accurate no matter what type of knife being used. Just a thought. 👍
I don't like that test very much because it can't differentiate between a polished and toothy edge. So even with a sharp knife you might not have a very good cutting performance
I couldn't possibly agree more. Further, the Bess test is only good for testing a blades push cutting ability. It completely ignores such things as micro teeth for instance where high vanadium carbide steels really shine. I can sharpen a blade so sharp and highly polished on the edge that it will score very low, shave like a dream but will not cut hot butter! I use to mirror polish edges to a fantastic shaving edge just for knife shows. Why? Because everybody seems to want to pick up a knife and see if it shaves. The next thing they do is bleed all over my table. So I give them smooth, shaving, dull knives! How can a shaving edge be dull. simple, No micro teeth to actually cut in anything but a push cut. Which in every day use is virtually useless except for preparing veggies in the kitchen. Issue is, without the micro teeth, when doing a working cut, the edge tends to simply slide on the material being cut. No Bite!

I got the one with the prewired clips. I used 5 clips and on one of them, the wire popped out of the clip. This was a knife that scored 100, or two sided razor sharp, so, it didn't push the wire from the holding clip. Not happy with purchase at all.
So true man!!! I’ve called out instagram ads for doing the test quickly and without averaging. Also I think the clips are much more consistent than the canister of filament, but they are spensive! Also your 39 is insane! 70’s is my best!
How consistent is the test Bess certified test media ? - I am testing high quality monofilament fishing line with =/- 5% deviation. - 100 tests with new out of the wrapper scalpel blade - Using a mechanical 10 to 1 speed reduction lever to minimize feed speed & variations in feed speed. - The mono filament line I am testing seems to be 50% stronger =/- 5% deviation.
I have only seen one guy on youtube using it to test factory sharpness of knives and he uses it honestly. It is only a guide after all, there are heaps of ways to see how sharp a knife is. A number is just a number.
I still am thinking of ordering one of these testers. Just to see if my sharpening skills are up to par. Prior my only concern was the leverage of the handle and the difference edges would effect the numbers, like recurve to a belly..
Thank you for this Public Service Announcement. My initial interpretation from the headline was that we should not consider purchasing this tool. I agree that accurate results are a challenge and that maybe people on the internet cheat. However I think this tool may still be useful as a gauge on my workshop. I would need to learn how to use it accurately and consistently so that I could use it as a metric of how well I sharpen. But I also agree it may be of little value to try and compare numerical values between other people or even between different knife styles.
They need to modify the scale so that it automatically applies a progressive load at a constant rate. I bet this could be rigged up for not too much? Use a load cell and RTC to record the g/s loading rate?
BASED, never crossed my mind. You would need to do a more controlled test where you knew the same amount of pressure was being applied every time and THEN average it as well. Wow, that's a "results may vary" if I've ever seen one!
How about testing multiple points on the blade? Seems to me that using the entire length of the blade to cut paper would reveal variations. But how can you put a number on that? I really don't care, because I like to see people showing off by cutting paper, cutting slices off blueberries, and doing other real things that I can try to duplicate. Great video!
Jerad is damn right about this! I for my part use cigarette tubes, for shits and giggles did I use this BESS thing once (a guy does the testing for 5€ each) I dont trust this number thats why I wont say it and I dont wanna sound like a flexer or anything, another thing is that I dont have proof for that (no video sorry....) I did it once and he offered me to do a few more on house because he couldn't believe it all in all I did 4 testings for 5€. But if you wanna check something Knife Grinders has a modified chart which shows that you can reliable whittle hair at the 100 range? (Im not certain at this moment) but they show what you can and cant do with the edge you have on your knife. Another thing is I found out the tester favors Mirror Polished 4k+ edges because essentially you do a pushcut and Coarse up to 3000k score way higher on the tester, which is a little inconsistency I discovered....
Yep, anything with a human element isn't going to be the most accurate thing around, especially when comparing between different humans. I'll use the thing for videos when I'm checking a blade's edge right out of the box. I do it in real time on camera and also depict my stringing of the filament so people can draw their own conclusions... but that does require their knowledge on HOW to properly utilize the tool to judge if someone's using it correctly or not. As you say, more often than not, people don't RTFM and maybe follow the techniques from other content creators that get those unrealistically low numbers. I'm immediately skeptical of any readings someone gets if things score less than 100. Usually you can see this if they show it on camera though, as the blade will have inertia and continue moving after the filament is severed. For the most part, I use it from time to time as a sanity check on my own sharpening. If I change something up in my technique/materials, or use a different system or stropping compound, etc I can see if it's effective, has diminishing returns or was regressive.
I think the most objective way to gage a blade’s edge is to examine that under a microscope. That’s academically quite interesting, but you don’t really need to do that, if what you want is a blade that cuts. Just sharpen that thing until it cuts the way you want it to.
Excellent education. As for this device. Create a pivot with arm and weight to put the pressure on. Could be done 3D printing. As well gives a repeatable force.
Well done. Any chance you could do a test between some double edge blades versus a straight razor. I just started wet shaving and getting a straight razor shave ready forced me to buy 3 higher grit stones. It's a new level of sharpening and a good stroping is essential. Thanks.
Something very coarse like a 180 /125 or similar with another coarse on the other side i forget which one i think its 100/80, then the 50/40 with the 20/14 on the other side
This is literally something I've been telling everyone i know that sharpens. Anytime you use the spool it's very easy to cheat the score to make your ego feel better. I prefer the clips because those tensiona are set by factory
On the internet if someone tells you the sky is blue you better do your own research because 99% of the time what people say and do is wrong or falsely informed
The only sharpness test I ever do is phonebook paper, against the grain. Sure, not super-dupper sharp. But that is my minimum standard. If it can cut phonebook paper, it can cut anything I usually cut, with ease. And it’s not TOO sharp where you’d lose the edge too quickly. And it’s fairly easy to maintain this said standard, freehand, with few strokes of a diamond rod, butcher’s steel, and a leather strop.
Another channel that uses one of those says that by putting extreme pre-tension on the wire, you can cheat too. It's why they use the single use inserts.
I don't use the device to see how *low* of a score I can get. I used it to gauge my sharpening process. It is quite fun, though, to see exactly how razor-sharp you can get something. I typically use it in a casual way and keep all of my knives in the 200-ish range, which is plenty sharp for whatever I do with a knife. The sharper the knife is, the quicker you will lose that 100-200 razor edge.
It's actually the opposite way, the sharper it is the more edge retention it has. What you lose is toughness so there's a balance so that your edge is not to brittle but sharper leads to longer cutting edge retention. Now certain steels will lose the bite much faster with a very fine grit which can come off as getting less sharp. I watch the majority of people who use this test cheat this test most people do not know what to look for or how it actually works which is why I made this video after watching dozens of people cheat the test
I’ve seen SO many people use this tester and straight up lie about how sharp knives are. Maybe they don’t realize, but it’s ridiculously off. So many Benchmade’s testing like they come with Hogue edges when we all know there is zero way that’s accurate.

Thank you for this, I’ve been seeing some ads recently for a certain sharpening system and it’s clear they’re cheating it on which bothered me a lot
If you tension the wire by 100g which is the manufacturers guidelines then even your 3 measures to get an average would probably be closer.

Great video. Thank you for doing this.
Fantastic vid Jared. Thanks
Very nice! I've seen a lot of misuse of these Bess tests, and it's irritating every time.
It should not be toooo difficult to develop a system that overcomes those problems. I wonder why there is none...
Thank you. Good to know. I think it should be easy to see if someone is doing it right or not.
Thanks 🙏🏼 brother, keeping them honest 👍🏻👍🏻
Very informative video, thanks for sharing
Dude, I love my mordax. It was cool to see you using one🇺🇲🙃
Oh damn thx for the info man
I have had a lot of questions about this… BTW first!!!
Yep, anything with a human element isn't going to be the most accurate thing around, especially when comparing between different humans.
I'll use the thing for videos when I'm checking a blade's edge right out of the box. I do it in real time on camera and also depict my stringing of the filament so people can draw their own conclusions... but that does require their knowledge on HOW to properly utilize the tool to judge if someone's using it correctly or not.
As you say, more often than not, people don't RTFM and maybe follow the techniques from other content creators that get those unrealistically low numbers. I'm immediately skeptical of any readings someone gets if things score less than 100. Usually you can see this if they show it on camera though, as the blade will have inertia and continue moving after the filament is severed.
For the most part, I use it from time to time as a sanity check on my own sharpening. If I change something up in my technique/materials, or use a different system or stropping compound, etc I can see if it's effective, has diminishing returns or was regressive.
I think the most objective way to gage a blade’s edge is to examine that under a microscope. That’s academically quite interesting, but you don’t really need to do that, if what you want is a blade that cuts. Just sharpen that thing until it cuts the way you want it to.
We all know a certain drop shipper who used to slam down on the tester. They’ve been called out and seem to use it as intended.
So what you are saying when used properly you get good results but when used improperly you will not.
Excellent education. As for this device. Create a pivot with arm and weight to put the pressure on. Could be done 3D printing. As well gives a repeatable force.
Well done. Any chance you could do a test between some double edge blades versus a straight razor. I just started wet shaving and getting a straight razor shave ready forced me to buy 3 higher grit stones. It's a new level of sharpening and a good stroping is essential. Thanks.
I WILL SEE WHAT I CAN PUT TOGETHER IF YOUR A MEMBER ON THE CHANNEL WE DO LIVE SHARPENINGS TWICE A MONTH
what grits would u recommend for venev dual sided stones if i were to get 2 stones allowing for 4 grits
Something very coarse like a 180 /125 or similar with another coarse on the other side i forget which one i think its 100/80, then the 50/40 with the 20/14 on the other side
Neeves keeping it real 👍🏻
What's the sharpening stone that you were using?
Probably Atoma, and Venev checkout the neevesknives store link in most recent videos or HAPSTONE link
Thanks for information
This is literally something I've been telling everyone i know that sharpens. Anytime you use the spool it's very easy to cheat the score to make your ego feel better. I prefer the clips because those tensiona are set by factory
On the internet if someone tells you the sky is blue you better do your own research because 99% of the time what people say and do is wrong or falsely informed
Oh, boy, this is going to cause a stir, but you backed up what you said.
The only sharpness test I ever do is phonebook paper, against the grain. Sure, not super-dupper sharp. But that is my minimum standard. If it can cut phonebook paper, it can cut anything I usually cut, with ease. And it’s not TOO sharp where you’d lose the edge too quickly. And it’s fairly easy to maintain this said standard, freehand, with few strokes of a diamond rod, butcher’s steel, and a leather strop.
Another channel that uses one of those says that by putting extreme pre-tension on the wire, you can cheat too.
It's why they use the single use inserts.
I have used both they are both super easy to cheat
It’s also not cutting, it’s breaking the wire. If anything it’s testing average tensile strength
Point taken. Thanks Jerad.
Thanks for the content I wondered if it was a trick to it.
J swinging hard at the air was funnier than I was prepared for.. I think a couple of them connected.
I find mine useful when I use it correctly.
absolutely
I don't use the device to see how *low* of a score I can get. I used it to gauge my sharpening process. It is quite fun, though, to see exactly how razor-sharp you can get something. I typically use it in a casual way and keep all of my knives in the 200-ish range, which is plenty sharp for whatever I do with a knife. The sharper the knife is, the quicker you will lose that 100-200 razor edge.
It's actually the opposite way, the sharper it is the more edge retention it has. What you lose is toughness so there's a balance so that your edge is not to brittle but sharper leads to longer cutting edge retention. Now certain steels will lose the bite much faster with a very fine grit which can come off as getting less sharp. I watch the majority of people who use this test cheat this test most people do not know what to look for or how it actually works which is why I made this video after watching dozens of people cheat the test
@@NeevesKnives I learn something every day!
I’ve seen SO many people use this tester and straight up lie about how sharp knives are. Maybe they don’t realize, but it’s ridiculously off. So many Benchmade’s testing like they come with Hogue edges when we all know there is zero way that’s accurate.
I've seen it manipulated and seen people in the comments calling them out on it.
I always took any results from this tester with a grain of salt because it relies so much on the person doing the testing doing it the right way
