Newbie seeks advice

[bushblade]

Hi,

I am making my first knife using the stock removal method and am hoping someone can answer a question. My knife will have a scandanavian style, flat, single bevel edge, and I want to know do I grind the bevel to its edge before heat treating, or do I do it most of the way then finish off after the heat treat? I am using 01.

Hope someone can help and thanks in advance.

Will, grind to about 1/32" edge before heat treat, assuming you won't be doing any more shaping afterwards. You'll have to grind off the scale after HT but that shouldn't require removing too much metal. Anyway, that's what I shoot for. I'd like to get it thinner, but suspect there might be uncool consequences like warping if I do. I'm not sure how the single bevel blade will react during HT either; this seems like an invitation to warp to me! But it must work, all kinds of knives out there like that.

With O-1 I have found, during my very limited experience, that there is about 2 to 3 mil that has to be removed per side after heat treat. That is if I don't leave it cook at the quenching temp. too long. The longer you soak the deeper the oxidization and scaling. Then the blade needs to be fine sanded which takes off more. I have been trying to leave about 40 mil at the edge before heat treat but end up with less.
