Video Transcription

okay so now I've changed to a red ceramic belt it's fairly coarse so that I can grind my initial blade profiling or excuse me my initial blade grind in and I've got a wooden jig set up here that we use in our knife classes and basically you just set the knife in the jig and it creates the angle for you you just clamp it in and then you begin to grind in your blade angle or your blade grind we'll talk about that as we go here in a second okay so here's our blade clamped into the jig and now we want to figure out where we want the ricasso or our blade grind to stop and I'm not gonna give myself a whole lot of leeway there as far as how far it goes from the handle before the blade starts I'm not gonna give myself much leeway there I'm gonna mark that on the top of the blank here so that I can see it from above when I'm grinding that initial grind line into the blade now one thing that I do is I adjust my belt with the tensioning

bring suits all the way over to one side on this side and then all the way over this side when I'm cutting in my blade in

and witness the news even prosper [Music]

[Music]

you see what we're sorry to get there [Music]

again it's very important to keep the blade cool all the time you can look at that profile line and see where you need to lay on the blade more in the grinder where you need to lay off of a little bit if you're getting too deep so we need a little bit more press with you they're kind of even this line out a little bit

[Music]

[Music]

more like that you'll get used to doing this it may take you a few times you may mess up a couple boys but everyone you make will come out better now if you don't want to do it don't let yourself get across the center line that's blaze that's part of the topside guys so once you take it to meet off of that thing go ahead and swap it out take it to the other side of the jigs it's like this being cognizant of where your ricasso is if you need to you can remark that ricasso on the top yes sir that you keep those even until late the night point in the jig the other direction the reason for having this hanging out a little bit on the front side like that so that when you are putting your grind in you can actually sweep a little bit away from the belt that'll help you on the front edge on the very front point view of your knife and then we just start again on this side adjusting our belt the other direction so it rides further over on this side and then repeat the process on this dog's a plate now one thing I will tell you is that when you're using a fish material or if you're using anything less than three sixteenths you're really gonna have to pay it pinches out hot it yet especially on the tips and the fitter that blade profile gets it easier it's and stuff you don't want to turn it boys yellow straw yellow that's okay you don't want to turn it blue so if you can you li put that thing in the water about every couple passes just to make sure you don't overheat your blade

now you're gonna start to develop a little bit of a wire edge here and that's kind of what you're looking for but you don't want to go anywhere beyond that for sure right now because you're gonna reheat this blade up to heat treat it in temperate and you don't want too much of that get that too thin and it won't heat treat rise it'll just get burble on you so now what we're gonna look at is we're gonna look at our ricasso to make sure it's even if it's a little off on one side we can adjust it and then we want to look at this angle here make sure grind is even on both sides so that should be a perfect triangle right there and then back here you can see our cos is a little off on one side to the other so we're going to adjust that right now by putting this plate back in the jig on the other side pointing it down and just coming in there just a little bit and adjusting that in the copy so we'll go back to the other side of the belt as well okay so here's our blade blank ready for the heat treatment temper process and now we're going to heat this thing up stamp our logo on it and then we're going to heat treat it and then we'll go to temper [Music]

now we want to make sure that we didn't bend the blade in eight when we did and then we'll put it back in the furnace for heat treat okay so what we're looking for now is critical temperature on the blade itself which means it's non-magnetic so if it won't stick to a magnet it's ready to be quenched so we're going to quench this in motor oil to affect let me get our initial hardness

we're dipping it all the way down to the blade leaving the tank sticking out and we're rotating it in circles and we're counting to 20 once it comes out of here we're going to lay it on our anvil to cool down before we temper the blade we'll bring some of the hardness back out
