- THIS PROCESS CAN BE DANGEROUS! WEAR GAUNTLETS, SAFETY GOGGLES AND AN APRON AT ALL TIMES!
Heat-treating a knife blade is actually quite simple, if you just follow 'the recipe'. There's lots of overly-complicated recipes floating around, so I thought I would show you a method that I've used and proven for O1 tool steel.
Here's a list of tools that you'll need:
O1 Tool Steel: amzn.to/1vF0nSo
Channel Locks: amzn.to/1DiN9vw
Bernzomatic MAPP torch: amzn.to/1wiHkvS
Canola Oil (get 3 or 4): amzn.to/1tzQGEF
Quenching container: amzn.to/1sXnsNX
Leather gloves: amzn.to/1wdYb0R
Safety goggles: amzn.to/1FcU7UA
2 Brick forge instructions: www.bladeforums.com/forums/sho...
(K23 firebricks for 2 brick forge, you can get these cheaper locally): amzn.to/1waUvhl
PLEASE NOTE: Doing things of this nature can be extremely dangerous. Use common sense and take every safety precaution to make sure you're not injured.
This provided the most clear instruction on this process that I have ever seen. Thank you.
+Donald Stockton Excellent! Glad it was helpful Donald!
I totally agree with you. I watched a lot of heat treating tutorials but there was no video that contained as much information as this one.
Hi from İstanbul. I just want to know the tempering degree and duration of CK75 (1075) steel if you have any idea of course.
Iam from the phillipines were can i buy your knife..i am an avid fan of your sir...hoping to hear from u...
There is a bit of a code to this:
The "W" in "W1" stands for "water quenching"..
The "O" in "O1" actually stands for "Oil Quenching"...
The "A" in "A2" stands for "Air Quenching"....
The "D" in "D2" means "Die Steel"...
The "S" in "S7" means "Shock Resistant"...
There are many more too, and a number of different systems used in different countries and industries.
OH, my god. Thank you for this info. I had no idea. I've learned 80 times more from your one video.
As an aspiring knife maker, I value your videos greatly. You go into great detail, giving as much info as one could ask, but also provide info at a level that someone looking to get into the craft can follow. Very well done - thanks a million.
thanks mate! glad the videos have been helpful!
I've been watching videos for months now about knifemaking with utter fascination. I recently discovered some of your videos and you are legitimately my biggest inspiration for the craft. Thank you, sir!
Good to hear mate! I'm glad the videos have been helpful!
You are so generous for taking the time to teach people how to make knives for themselves with detailed instructions. I appreciate your videos a ton and I will be sure to recommend your channel to all of my friends that are interested in knife-making/knives.
Thanks for the king words mate! I find it very gratifying to help people get started, hope the videos have been helpful!
Just planning to get into this and I must say.....I've looked at a lot of "forge" vids and yours is the clearest and simplest....And you're the ONLY one who recommended having a fire extinguisher handy!
+Mark Werner Nice! Thanks Mark! Hope the video was helpful!
I just want to say thank you. Your videos inspired me to make knives of my own, and they are infinitely helpful. Keep being awesome, and please keep posting more stuff!
That was one of the most concise heat treating videos ive ever watched! Thank you for sharing!
This exact process should work just fine for a number of steels including: O1, 5160, 1060 1070, 1080, 1084, and 1095.
It won't work for stainless or high alloy steels.
Be warned though that this is a fairly simple heat-treatment scheme and that you likely won't be getting the full performance out of most steels. It will be good enough for getting a first knife done though! After you're comfortable with the process it's worth the time to learn a bit more about steel and how to heat-treat it.
And invest more in tools.
Hey Patrick! Thanks for subscribing.
I generally recommend O1, which is the steel I'm demonstrating in the video. Using this heat-treating process will not get you 'the best blade in the world', but you'll get a knife that's perfectly serviceable.
The reason I recommend O1 is mainly because it's kind of hard to make a mistake with it. Most of the other 'cheap' steels (like 1084) require fast water/brine quenches which can cause cracking and warping if you don't do exactly the right things.
Thankfully someone knows that you can't harden basic steels in stuff like canola oil. Maaybe if it's thin enough. 52100 from ball bearings is also a slightly slower quench thanks to some chrome.
i love the simplicity of your designs, function defining form, not form limiting function.
Thanks mate! I truly believe that knives are tools and are meant to be used, that view definitely influences my designs heavily.
Glad it helped! It's not the be-all and end-all of heat-treatments, there are other methods that will get more out of the steel, but this is a very good way to get started.
I have learnt more about knife making from your channel than all the other YT videos combined, you have a natural way of simplifying and teaching the steps. So glad I stumbled upon your channel!! By the way, are you an Australian? Living in Canada now I guess? (sorry, not being nosey or anything, just picked up on the accent)
castortroy365 Thanks man! Glad the videos have been helpful!
Your guess is right on! I moved to Canada in 2006.
The temperature where steel turns non-magnetic is called the 'eutectoid point', in some steels this point corresponds with the right temperature for heat-treatment (1084 and other spring steels for instance) but unfortunately that is not the case for O1. You have to go at least 50º hotter for O1, which is why I mainly talked about the color of the steel.
Using a magnet can be helpful too! Just be aware that you have to got a bit hotter than the magnet says.
Thanks! this is a very useful tip! thanks for being so cool! I love your channel!
Crystal clear instructions without wasting a second. Thank you.
+mdirtydogg you're more than welcome mate! Glad the video was helpful!
2 years ago this was the first gough video I watched. It inspired me to make my own coffee can forge to treat some 01 steel. Now you are making the most beautiful knives on a milling machine and HT with your own oven. I LOVE THIS CHANNEL! Thank you so much for your videos.
+Travis Cox Thanks very much for following along Travis!
hi, just watched this,i will be pinching all your ideas and will make them my own,lol. i love your furnace, simple,and amazing.keep up the good, no, great work.
and fyi, methril and stardust are now available in walmart,you just need to be with a qualified dwarf from isingard whose second cousin needs to be a leprechaun to be allowed to buy it, ( for the makers of fairyblades) hope this helps.
Could you make a tutorial on building a forge?
It's on my to-do list, but it will be a while most likely!
@@GoughCustom so, do you have a video for it now ? sorry this is the first video i watched
Thanks mate! Sounds good! Always nice to put the finishing touches on those projects!
Thanks mate! Really glad you found it inspirational! I'll keep posting videos, don't worry!
would the process be the same for 1084 or 1095 high carbon steel ?
+J woo Yes, both of those steels can be heat-treated using this exact same method.
Absolutely fantastic, I am so glad I found you by way of Trollsky. I am happy you took the time to show people how to set up a cost effective forge and how to use it, along with the cooling. This gives me much more hope to be able to set up my own now.
Awesome! Glad I could help!
It's worth noting too that you can substitute other heat sources. A charcoal BBQ works well for instance. (with lump charcoal)
Thanks Dave! I actually made the hole the same diameter all the way through. Initially I had it smaller, but it seems to work better if you just make it the same the whole way as the flame swirls more nicely.
No worries! Glad you liked it!
Thanks mate! The positive feedback keeps me making more videos!
Thanks, really easy to understand when explained properly, you would have made a good teacher. Your videos are the best I have seen and I think I've watched most of them on here. Keep making videos your a true knife making pro.
GAN Thanks mate!
No worries! There definitely seems to be a lot of bad information floating around about heat-treating, so I figured I would make a video that tried to explain how to do it with all the complexities stripped away. Glad you liked it!
Thanks for explaining the safety precautions and the clear reasoning for each tool used. I'm excited to give this a try!
No worries, glad the video was helpful!
Nice, clear video on heat treating steel. I like the wine bucket idea, as I have to treat some small skinny tools and don't want to use a lot of oil- Perfect solution! Also that is about the greatest DIY small forge I've ever seen! ONYA!
+Jean pSmith Cheers mate!
Thanks Dustin! Glad you found it useful!
Thanks mate! They can certainly be a lot of work, but I enjoy the process and the end result, definitely planning on making more!
another great video mate I will say it again you are a craftsman I like the simplicity of the forge and will try this myself thanks again for your time and knowledge
No worries mate, thanks for watching!
Love your videos man. Clear, informative, and to the point. Thanks for posting!
No worries at all Sam!
Hey Aaron, I have subscribed to your channel recently and must say that I think you ROCK man. So many helpful tips. Great of you to share info on knife manufacture and the like. Keep it up.
Video was extremely helpful. Thanks.
And thanks for even providing links for example tools and materials used.
Garth S No worries mate! Glad you found the links helpful!
Thank-you! And no worries! If you have any other questions just post them here!
Thanks mate, it's appreciated! Many more videos to come!
Just hardened my 4th blade using this method. Thanks again Aaron for all that you share with the knife making community. You rock! =)
+Marcus Santer Nice work Marcus! Very glad the video has been helpful!
Finally, a good understanding of tempering and hardening. Thank You!
+WVoutdoorsman100 no worries at all mate!
Excellent video, you explain everything very well. I have a few 01 blades finished I need to get heat treated, may finally get it done.
I would love to! It's something I'm planning to do in the future.
Thanks mate! Glad you liked it!
I've made your jig for the flat grind...and I loved it, BTW it works amazingly,
I've even made a mod version for longer blades
Thank you
jujijo16 Glad it worked out for you mate!
Thanks! I think that design is a really great all-rounder!
If only all UA-cam tutorials were this comprehensive. 👏🏾👏🏾
Excellent videos and beautiful knives, a true craftsman you are!
Starfire Technology Thanks very much!
Thank you! You are very kind to teach us these things.
No worries mate! Thanks for watching!
Great stuff, as an apprentice 1961 with Harland & Wolff, Belfast, we did a lot of metal forging & annealing, in the 1st year training school, this brings back a lot of old memories, our tool shop was more in line, with Noah & the Ark, I think if they had you on the titanic it would never have gone down, you & tutors like are doing the world a fantastic wonderland service, thanks & cheers, thumbs up again
Cheers mate! I think it's important to teach people this stuff!
pretty cool, i havnt seen the process demonstrated in quite this way before and it makes me think of ways i could improvise other manufacturing techniques using more common items
There are definitely lots of cool processes that you can improvise at home if you're willing to take your time! UA-cam is such a great resource for things like this!
Glad to hear it!
PERFECT video! Direct, to the point, and with no unnecessary blah blah blah. 1-even cherry red 2-test hardness 3-400 degrees for 2 hours. Done! Thank you very much for sharing your knowledge
Ken :-)
+ken barker Thanks Ken! Glad you liked it!
Aaron, thanks again, man, for your clear description of this process.
🇬🇧🤍🇦🇺✌️
No worries at all mate!
Hi, I can't help but thank you, I'm starting to make some knives and your information is really valuable.
Thank you for your efforts. We have been working on three knives and have just heat-treated the first two and I am heating up the oven right now to bake it.
Great videos!!!
Awesome! Hope it goes well!
great straight forward video, clear concise instructions, hats off to you fella !
Glad it was helpful mate!
Thank you! now im feeling much better about attempting this on my own
Dude. What a great video. I have been wanting to learn how to temper O1 steel for 4 years. I make dies for swaging and reloading ammunition. Have used Grade 8 bolts because I thought heat treating was too complicated. Now I can use the proper steel and make far better quality tools. THANK YOU
Glad to hear the video is helpful Dan!
Great video! Excellent flow and excellent explanations. Thank you very much, I subscribed and saved to watch again.
Thanks mate! Glad the video was helpful!
after watching a couple of your vids i built a jig and am starting to make a couple knifes, and man is it a lot of work, thanks james
Hey James! Yeah it can definitely be quite a lot of work, you'll get faster with more practice though!
For sure! That's something I've been meaning to do for a while anyway. I'll probably look at doing that later in the week or over the weekend.
-A
Your videos are very informative and interesting thanks for sharing. It is something I would like to try
+Iain MacKenzie No worries at all mate, I hope the videos are helpful!
Thanks! Hope you found them useful!
UA-cam is amazing place full of awesome people like yourself. People who helps others like me.
Subscribed and liked your channel. Thank you for your work and videos!!!
No worries mate! Thanks for the kind comment, I'm glad the videos have been helpful!
Just wanted to add yet another thanks for a great video, I've been afraid of trying to heat treat myself, but this vid has given me the feeling that I can do it, so thanks!
You can definitely do it! With simpler steels like O1, 5160, 1084 and 1095 it's really just not that hard!
Best Explanations I've seen. Thank you!
Glad it was helpful!
Love this guy!! The only teacher youl ever need.
Haha thanks Mr. Wombat!
@@GoughCustom welcome sir.my channel is full from favoriting all your videos.you've tought me alot.a great teacher
Great!
I'm going to work on that. Thanks for help.
And great videos you got there. Keep it up.
Thanks
Best of luck!
Thanks for an excellent video! This is the best I’ve seen for this part of the process!
No worries Scott!
Thanks! Hope it was helpful!
Excellent safety tips. Keep it up. Very interesting video
+Farshogard Dumasia Thanks mate, I will do my best!
I love all you videos. Thanks for helping me so much.
No worries Caleb! Glad they're helpful!
Man, another excellent video! Instructive, clear and concise. Thanks... again! Subbed, and looking forward to more like this.
Cheers mate!
Totally agree!
Great video and very helpful. Kudos for the fire extinguisher suggestion as well. Surprising how many people are unprepared for this event.
Thanks! Glad you liked the video!
Nice! The 2 brick forge really is a great idea, the guy who posted it on the net originally should be very proud of what he spawned!
Great to see another aussie making excellent knives nice work mate. Love your forge idea been stuck for awhile trying to decide and yours makes the most sense tha ks alot brother take care.
+James M Cheers James! Glad the video was helpful mate!
Very helpful. I new very little before I watched this video. Now I feel that I could safely temper a knife. Thanks!
Excellent mate!
Thanks.. ☀️
Its so fun.. Just starting making a small knife, getting the tools, and startet to graunding yesterday.. Uhh very difficult, but I think I can learn.. Love your videos, and that you show, and not have looooong explor.☃
Regards from Sweden
+Søren Lauritzen Best of luck Søren! I am sure you will do well, it just takes some practice!
KISS, is the saying and you achieved that in this vid. Well done Gough. Thumbs up.
Cheers!
Very good instructions! awesome! Subscribed!
Thanks mate! Welcome to the channel!
that forge is pretty brilliant.subscribing!
Thanks for taking the time to make this. There is never enough how tos on heat treating
Glad it was helpful!
I like how you devised a statistically sound random test. This is a very informative and systematic approach.
Thanks bud!
Yet another great and informative tutorial Thank you Aaron! :) keep um coming!
This is an awesome tutorial, glad I ran across it!
Glad it was helpful!
Very interesting stuff. Part of the reason I am thinking about doing the "edge quenching" is because im not sure if my homebrew forge will get hot enough! It may be easier to just get the edge and grind (saber grind) nice and hot while leaving the spine unhardened. Thanks alot for the informative and prompt response. It helps alot!
No worries! Hope you find it useful!
Definitely interested! Post it as a video response to my heat-treat video when you're done!
Very awesome. Well done.
Simple and extremely clear. Thank you,
You're very welcome Donald!
thank you a lot, you're awesome. keep on going, best information I could find.
+Geert Perton cheers bud!
Excellent instructions. Thank you!
No worries!
very good video, clear, concise, and accurate
g1moore Thank-you!
The bricks are quite delicate yes. I made the channels by cutting out a triangle shape with an old handsaw, then using some rough sandpaper (36 grit) attached to a wooden block that was the right shape. A little slow but it worked very well!
Simple and most informative. Thank you
+Christos Papakostas you're welcome mate!
Thank you very much Brotha! Super great and informative video!!!
seagangsta b Thanks mate, hope it's helpful!
Hey mate!
The case for the firebricks was made from some scrap sheet steel. It was basically cut to size with a cutting disk in an angle grinder, then bent using a cheap sheet bender (you can use lots of stuff to bend thing sheet, have a look around the net for that part).
The sheet was then drilled and pop-riveted together once the bricks were put in the case.
Love your videos and knives. Good work! Thanks
Also, like the style...
Thanks very much mate!
