So I heat treated my first L6 knife last night. I havent even bothered to measure the blade length but it is around 3".
I heated it past nonmagnetic with my girlfriends Mapp Gas torch. (She was in a metal sculpture class and we started talking about knives. I currently have her fooled, she thinks I am cool for making knives and doing 'metal sculpture'. She also gave me a bunch of files she didnt have any use for!)
I then quenched in veggie oil at 150 F. And tempered in my oven at 425 for 2 hours before turning off the oven and letting it cool.
It is kinda funny, after buying a oven thermometer at Wally World and finding out that my oven (in my kitchen) is 100 degrees higher than what it says it is, I no longer burn food, and it really can go up to 600 degrees in that thing!
I didnt profile it closely enough to a edge before heat treat and now it is giving me hyell to get an edge.
The style is what I would call a modified scalpel, perhaps a "street scalpel"?? A cross between a work knife, a chisel point tanto and an exacto knife if you will.
Oh yeah, one more thing, all grinds are convex. I learned all about this type of grind on my khukris and now just about everything I own wears one.
If I did this one right, it passes my sharpness and durability tests, my GF wants to carry it. How cool is that? She is going to a glass school this summer up in Seattle and will need a knife to do something I dont quite understand with stained glass. I think scratching it so that there is a line where it will shatter... or at least that is what I understand from it. So I attempted to make this one rather hard.
I hope I can get pics up later on and I can show you guys my work in progress.
(This is the first knife I have given a heat treat to, and that I havent ground out of another broken knife.)
