- This is my take on the epic debate of scandi vs convex grinds. I don't think anyone else has a test that compares two nearly identical blades but in different grinds. The test was closer than I thought it would be. Remember this is comparing how well both knives do the tasks.
Great review. In the end I prefer the convex as it cuts through my steak like butter and yet can do the bushcraft tasks comparatively similar to the Scandi. Also I find that convex holds an edge much longer and we all want to be using the knife rather than sharpening all the time. So for me the convex is a clear winner, but that’s my opinion and certainly not saying that my choice is the right answer for everyone.
One of the best comparisons of the 2 out there. Great job!
I've carried and used both grinds . Very much agree with your comparison. I've studied and read as much of Horace Kepharts works and you've basically shown what he described as the reasons he chose flat grind with a convex edge . Obviously either will work well .
I'm a (2) knife guy when it comes to the woods. I'll take a convex or scandi-vex along with a good flat grind knife. The flat grind is a backup and food prep knife. The others are general camp chore blades and wood working.
Well made review, thanks for taking the time. I use both edge types and I have a weakness for the curvature of a convex edge. It just looks nice. Nice to know the conclusion is that they are very close in usage.
The difference in width is quite noticeable in width. It looks like much more than a difference of 1/20,000th.
willieboy3011 Jonas it’s .020 of an inch difference. I’m taking in machinist terms.
I agreed visually looked that 3v was a lot thinner.
I’d go scandi for wood and convex for everything else although scandi grind sharpening is probably the easiest grind to sharpen its hard to mess up sharpening a scandi grind convex u need a little practice to keep it convex and get the right angle unlike a scandi.
I would expect a scandi to do bit better in woodwork, and the convex to be slightly better in food prep, since food prep falls in the "anything else" category. There's not much point in asking what's "better" so much as what's better for what job. People who lived their lives in the outdoors did the sensible thing and had multiple tools. My understanding is the Sami had a big knife for chopping and so forth and a smaller one for cutting. The mountain men in the 18th century had knives and hatchets. If I were out with folks bushcrafting for a week I'd take a knife suited to that but I'd stash something, maybe a bigger Opinel, with my gear and leave it at the camp for food prep. If that's cheating, well, I guess I'd just go ahead and cheat. : )
Nice comparison bud! Thanks for sharing.
When it comes to knife grinds, I am preferential to high saber grinds, that are on the thin side behind the edge.
My favorite knife is a modernized and militarized puukko, it is thin behind the edge, and it cuts incredibly well.
That’s one of the reasons convex works so well. You have better behind the edge thinnest than scandi.
Watch some of that Japanese doctor's old video's -- Virtuevice? He's got loads of scandi vs convex comparison videos. He came down on the convex side, but I think it probably depends on application. Slicing paper not really a real world application. His UA-cam tests tended to be things like batoning and feather sticking, but he was actually using them primarily for dressing deer.
@@twatmunro now that I make knives and have time to experiment I understand the appeal of scandi more. However it preforms best in steels 3/32 and thinner. There’s also a lot of bad convex grinds out in the world. Scandi is decently consistent from blade to blade and from manufacturer to manufacturer. There’s a few degree variation in the bevel angles.
Great Review. Convex all the way. I'm no expert when it comes to sharpening and find a convex more forgiving when it comes to sharpening angles.
@@LubberKing incoherent dribble
Which is better . . . scandi or convex grind?
The answer is hollow grind (at least when it comes to slicing softer materials).
Sure you could say that I don’t think a hollow grind would hold up very well to harder bushcraft tasks. If you want to get super technical we could say a double hollow grind or an S grind is better.
@@TheScrawnyLumberjack For hard use stuff like batoning wood, I typically use a thick saber grind knife. For feathersticking and tinder scraping, I go with the scandi grind. For food prep, I prefer hollow grind or full flat grind. I do own some Bark River knives (supposedly all Bark River knives are convex grinds) and they do work well for brush clearing and chopping tasks. The main benefit I've noticed with convex grinds is that they hold an edge much longer. They however don't reach the crazy high levels of sharpness on the BESS sharpness scale that hollow grinds and flat grinds do though.
@@BigDaddySwingingMeat a zero convex can have an issue reaching crazy sharp levels because it’s just easier to round over that apex on a microscopic scale. I wouldn’t use bark river as a bench mark for how well a zero convex performs I doubt their heat treat very much. Now that I’m making knives I typically go with a convex primary and small V secondary. Convex has so much variability to it though which is the one trade off. There are few really good convex grinds out there and many many bad ones. Currently I’m using a convex ground blade with V secondary sitting at about .005 behind the edge that can do any bushcraft task I need well. Food prep is another story because grind for food prep can be very complicated depending on the performance you’re looking for.
@@TheScrawnyLumberjack I have indeed heard horror stories about the poor quality control of Bark River knives in the past. Funny enough, I watched a video about that issue here on UA-cam about a month ago. I only own 2 Bark River knives and thankfully they seem to have received good heat treatments and had a great fit and finish. I've noticed quality control issues with Ontario and Condor too in the past. I buy a lot of blades from custom knife makers so if you happen to have a link to some of your knife designs I would be interested in taking a looksie and maybe purchasing. Thanks.

By your review, I think the convex is better than the scandi, I have Falknevin F1 which one use convex blade,also I have the Mora eldris which one use scandi blade, I prefer F1 more. Thanks a lot about your nice review. wonderful!
Thanks Alex, I intentionally left it a bit opened ended with the hopes people could draw their own conclusions. At the end of the day both grinds will cut but convex will have better performance. The problem is there’s a lot of bad convex grinds out there that renders this statement untrue.
You going to do a video comparing the sharpening process of these two grinds?
Malachi The Red I can do that.
Hey, you said you would! I would be interested in seeing that!
Great vid bro! I'm subscribed now!
Nice. Those adventure sworn knives r good knives. I've come to realize that different grind shapes mostly come down to intention, use case, technique and personal preference.
I prefer scandi-vex. Basically take a scandi and blend the transition corners. Convexing by removing from the shoulder, not the edge.
Awesome knives! Great review! My vote: Scandi!
Lucas Barbisan it was such a close call that in all honesty either will work almost just as well.
I have better experience with my Convex but that might also be because its A2 tool steel and holds an edge better
and most of all it just a more comfortable handle for my hands.
In my experience with the two grinds like the test they are so closely similar its hard to say one is better than the other.
My thoughts exactly. I'm liking the idea of carrying a 5/32 convex and a 3/32 scandi and the ultimate combo.
And to support your idea that scandi might be easier to just pick up and feather stick, I know when I got my convex and my girlfriend was playing around with it doing feather sticks she said my older scandi was much easier. Her having less experience with a knife. So seems for someone much newer at knives scandi might be easier.
Although I find the convex easier but again probably because its much more comfortable in my hand as my hand just barely fits on the scandi.
Joe Chitussi I think the larger bevel gives more of a area to use for indexing. I know when I first started I didn’t have the blade control I have now. Which is why I think feathers with either are easy.
Scandi + Vix (Outrider) or Convex as balanced single item option.
Thanks for the video, enjoyed it. 👍🏽 undecided!
Scandi is just the latest fad. It’s a good grind but so are the others. I’m personally not the biggest fan of it . But I get its pros and its usefulness…
I've never owned a convex blade...so what happens when there is no more sand paper and mouse pads in the world, do you just use a stone and a v edge? Can convex not be sharpened the traditional way on a stone? what would you do in a end of the world situation? does it even matter what edge you go with?
Den Smith well I don’t use mouse pads so I’m good there but I do use sandpaper. You could use a stone to sharpen convex it just takes more skill. You could also just put a V edge. I’d say in an end of world situation if it’s sharp then who cares what the grind is.
Yes a convex ground knife can be sharpened the traditional way. It's just very easy to maintain on a slack media like strops and a sandpaper/mousepad combo. But you can maintain all grinds that way. I have used every grind under the sun practically. And I prefer convex ground knives. In particular large knives. A lot of meat behind the edge. And it cuts well. I bought into a group buy with some friends back when Busse Combat had the Basic 8 out. The standard coated model was full height flat ground, secondary bevel at 20 degrees per side. And the LE model was full height convex ground, no secondary bevel, no coating. The cutting ability the convex knife has over the flat ground was very noticeable. In all facets of cutting/chopping/slicing. A full height convex ground knife does very well in most applications.
All knives hundreds of years ago were convex, as modern age has developed we now have more options. Any hand sharpened knife by stone will eventually become convexed from the natural rolling of the human wrist when stone sharpening.
@@Airik1111bibles only if you don't know what you're doing.
I've found that once you establish the convex geometry you can sharpen with regular stones by keeping the blad stationary and moving the stones along contours of the grind, as opposed to a flat grind where you would move the blade along a stationary stone.
Who is knives manufacturer? What models? Thanks.
Both are good as well as pretty looking
İt may depend on ones ability w.one or the other
Interesting video. Thank you
Try sharpening a convex grind correctly though. Few can do it.
That’s because people think it’s hard. People over think it to the extreme. It’s not any harder than a scandi and it’s way faster.
@@TheScrawnyLumberjack Maybe I watched a difficult method but correctly sharpening the convex curve up the side of the knife looked difficult to get it even with the correct amount of material removed.
@@1diggers1 when replying to your comment I was thinking I should do a quick video on my method.
@@TheScrawnyLumberjack I'll watch.
Go watch the Dutch Bushcraft boys on sharpening a convex. I find it very easy and forgiving edge to sharpen
There was a very famous Viking warrior whose wife kept bitching at him and he finally had to use this exact type of knife on her. The whole affair was quite SCANDI-lous!!! 😝
Hey My friend! Awesome video! Thanks so much for sharing!
Stay blessed!
Love these knives, but disappointed in this video. You can edit and ad on/redo the tests if the battery runs out. Why wouldn't you redo the Convex carving test? I was really looking forward to seeing how these to do head-to-head. Bummer.
I'll go with scandivex 😂
scandivex is convex
Paper has grain just like wood. It tears because you are going cross-grain -- or starting cross-grain.
I’ve never had non specialty papers only cut in one direction because of the grain. Rolling paper can exhibit such a behavior. I’ve never seen a discernible difference with computer paper, news print, or catalog paper.
Haha, chicken-patina! 🤣
I've become burnt out on using scndi grinds , knives are used for way more things then just feather sticking. The bushcraft scene has become so commercialized and the scandi grind has been way over hyped. I fell into the train of thought that all bushcrafter knives must be scandi or convex but have now changed my views. I prefer a full flat grind or thin saber grind both are excellent but I prefer the saber for batoning and overall toughness. A nice full flat grind is actually better than a scandi IMHO esp with food prep scandia mainly have one purpose wood whittling notches.
I use the Ontario SK5 Blackbird for everything and I have more control with it over a scandi grind now....Two years ago I would have totally not agreed with that opinion but through lots of use I've changed. Honestly its a personal preference thing and with any knife it's about using them and your own skill growth. My two favorite knives now are the Gerber Prodigy/Strongarm and my Ontario Sk5 I sold all my bushcraft scandi blades and only have a Garberg which doesn't get used anymore. I still like a scandi they can be fun but the way I use a knife now just clashes with my style, its so weird feeling cause I used to hate full flat grinds.
All my knives get a convex to the edge so convex blades are just a natural outcome of sharpening by hand. Nice blades bro😉
Only convex☝️
I don't see how you can make a useful test of two different edge profiles using blades made of different steels of VISIBLY different thicknesses. Your "test" is fundamentally flawed from the start. And given the wide array of tasks knives can be tasked in, it's rather presumptuous that you think you can make a determination of which grind is "best" because you've approximated only a tiny fraction of the things these knives might be asked to do.
@@chuckschillingvideos so basically you’re team scandi and are upset that convex is more versatile?
This comment gives me 1095 fan boy vibes. You’re saying that scandi might be better at one or two tasks in comparison to convex there for it can’t be quantified one is better than the other but that’s not the case. If convex has higher levels of edge stability therefore cutting longer that makes it a better cutting tool. If it’s tougher and receives less edge damage it’s a better cutting tool. It can be objectively determined on overall performance and utility. Just how super steel is better than basic high carbon
@@TheScrawnyLumberjack I'm not on anyone's "team" - I've just realized long ago that there are reasons for just about everything and that the reason different edge grinds exist is that they serve a distinct purpose. I find that more helpful than your silly presumption that one particular edge profile MUST be the best for EVERYTHING and not even be intuitive enough to realize that their "tests" are filled with bias.
@@chuckschillingvideos scandi does one thing really well and that’s wood carving. Why does it do it well it’s because the apex angle is more acute than a typical knife with a saber or convex grind. Run a convex to the same acuteness and it will out perform scandi all day. There are tons of uncontrolled variables but there are also nearly zero videos comparing these grinds side by side in the same model and nearly the same stock thickness.
@@redbeard5404 Oh ffs. I'm not a "fan" of any particular steel. I own knives of many different steels, including powdered steels like ZDP-189. There be fanboys in the room - but I'm not one of them. You need to look in the mirror if you're going to talk about fanboys.
…. Scandivex…..
The steel needs to be the exact same thickness, and the same steel to have the best results. This isn't a test... it's you showing off the fact you have 2 adventuresworn knives that you spent 900 dollars on
Given no one else had at the time attempted a comparison and I’m not sure anyone else still has. This is as close as I could get it’s not like I’m comparing 5/32 to 3/32. Also I think your math is skewed by jealousy perhaps? It’s more like $700 maybe less even. I could go find the sales records if you need them. To be super fair they should’ve both been made at the same time with the same handle material. I should be doing the test blind folded so I can’t be bias about which one is which based on sight. Just because the grind you wanted to win didn’t win doesn’t mean you should be but hurt about it. The cold hard fact even after all these years is convex does better over all because of the primary bevel geometry. A good convex is difficult to find because of the variability with the grind. Scandi does well in some situations because of the acute bevel angle.
Tie your boots better we don’t want u to trip and get a booboo☹️😢.
This whole video I could tell you were biased
Ira Hartford oh yeah totally with out a doubt since I did extensive testing before even shooting the video I already knew the outcome. All tests were done several times. It would be crazy to think someone would just shoot a short comparison and come to a concrete conclusion doing it once. I always keep an open mind and would never dismiss either grind.
quit watching at batoning..
