    Yes I did learn something, thanks. Well done presentation. I have to admit I'm that guy who doesn't "follow best knifemaking practices", mostly due to available resources. That said, I fully understand my blades don't live up to their fullest potential. However, Ive spent a lifetime cutting stuff for work and play with many different knives, and mine perform well. Could they improve,,no doubt,,and I'll continue to strive for better. Thank you again for sharing.

    Thanks Dennis on the very informative video 🤘 I've been on a 10 week wait for my oven for about 3 weeks now. I opted to get that over a 2 x 72. I started really learning and practicing using 1095 and canola oil and it skates a file 😆 but for me it's more of learning the processes at the time and just giving the knifes away to family. Now knowing I can do the work and produce a blade next for me before any thought of selling is using the right quenchent, proper soak times etc.. I can't wait to unpack my Oven!

    • @TyrellKnifeworks
      @TyrellKnifeworks  Před 3 lety +1

      The oven is a total game changer! I should have added in the video that if you're just doing knives for yourself or as a hobby for some friends, that its totally fine to use whatever and "it skates a file" is a fine answer. Its once you plan to start selling knives that I think it's an issue. In my opinion you shouldn't be advertising "1095" unless you used the proper quenchant because its more like 1080 if you didn't.

    • @TyrellKnifeworks
      @TyrellKnifeworks  Před 3 lety

      Peanut oil is just ok for 1084. For 1095 it’s not really very good. It’s kind of a waste of the 1095 because you’re not getting all the steel offers. You are better off sticking with 1084 if you are going to use peanut oil. If you’re just playing around and it’s a hobby, no problem. If you plan to sell your knives, I wouldn’t market 1095 unless I used the proper quenchant.

      @TyrellKnifeworks  Před 2 lety +1

  • @davidostertag7689
    @davidostertag7689 Před 3 lety

    Great video. One question: I make a lot of thin knives from 1080. Is it ok to use canola oil if the blade is less than 2mm thick (since the thin knife cools faster) or should I still invest in some parks-50?

    • @TyrellKnifeworks
      @TyrellKnifeworks  Před 3 lety +1

      You CAN use canola, but Parks is better and will give you a better blade. How much better? You wouldn’t know without an hrc tester. Might only be .5 - 1 hrc difference. 🤷‍♂️

    @scorpio0281 Před 3 lety

    I'm just getting started into knife making. The main steels I have always wanted to work with are 1095 (one of the forgiving steels) and D2. I have several D2 mass production knives that I love and have wanted to take a few features of this one, add to that one with another one's handle profile type of thing. My question is, would you treat D2 like O1 for quenching or does it fall more towards the 10 series steels? I was really hoping your video would show this as one of the steels, but understand you can't cover them all without the video being a full feature film length! 😆 I only ask here because I find it more useful asking someone that actually works with may steels more useful than 'hey Google' and getting God knows what for an answer.

    • @TyrellKnifeworks
      @TyrellKnifeworks  Před 3 lety

      D2 is an air hardening steel and the HT is much like stainless with aluminum plates. It’s a major pain to work because of the air hardening. Until you get some experience I would stay away from D2. You’ll likely need an oven to heat treat it properly. D2 is really a tool steel and there are better steels out there anyway. 80CRV2 is great and easy to heat treat. I’ve never even dealt with D2, though I just purchased some for some drifts and punches for a future project. Get yourself some 80CRV2 or 5160 or 10xx series until you get an oven (assuming you don’t have one) and more experience. Good luck and thanks for watching!

  • @Bar_D_Forge
    @Bar_D_Forge Před 2 lety

    I've used the factory's recommend heat treat from New Jersey steel and noticed that they recommend to put in during cycles at specific temps, like up to 1650 then cool to 950 and re heat to next cycle... Do you do that? And I'm getting even heat oven since I learned the forge is a bit much with dwell times, so how do you accomplish that heat regulation? If my oven is at 1650, how long does it take to cool to 1550 before I can put blades back in? Thinking I should get vermiculite bucket to stick blades in to maintain temp while oven cools... Thoughts?

    • @TyrellKnifeworks
      @TyrellKnifeworks  Před 2 lety +1

      I have my specific heat treat recipes (see my Heat Treating video). Only for stainless do have a stepped heat treat. I’ve never heard of hearing to 1650 then cooling to something like 950 unless that’s supposed to be the equivalent of “cool in still air”, which it might. An oven will cool from 1600 to 1500 just by opening the door. But getting it to 400 will take over an hour or more. Checkout my video on heat treating and try those. 👍

    • @TyrellKnifeworks
      @TyrellKnifeworks  Před 3 lety

      The problem is that *most* but not all leaf springs are 5160. *Most* but not all files are 1095. You're still dealing with unknown steel. I'm a firm believer in using known steels, particularly if you're going to sell them, but as long as you're honest with your customers about what you used, its fine. Happy forging!

    Hi, i would like ti ask why do You do, for example, the las normalization of 5160 at 1250F? Because i think that at that temperture You don't austenitize the Steel so You don't get an smaller grain structure. Sorry for mi English, i'm from argentina. I wait for your answer, have a Great year!!

    • @TyrellKnifeworks
      @TyrellKnifeworks  Před 2 lety +1

      First off, the grain reduction steps should be done below the austenizing temperatures, not at it. If you read Dr. Larrin Thomas' articles on the subject, he did tests and a normalization cycle (at higher than austenizing temp) followed by multiple grain refinement cycles that are lower than the austenizing temp gives a better hardness and grain structure. My heat treating specs follow this. If you watch my Knife Steels 101 video, I update my heat treating steps in there as well to add a sub-critical anneal after the grain refinement. Thanks for watching.

      It says right in the application for FiF that you should know forge welding, damascus, canister damascus, how to use powered forging tools (presses or hammers) and a lot of other aspects. The show isn't meant for hobbyists who play around and aren't serious. I still can't believe I see people on there who say they haven't done damascus (like last night's episode). How were they even accepted for the show!? And yes, I've applied and I'm still waiting for my call. 😜
