    Hey I am just getting started with knife making and iam looking into making my first blade.(I have rehandled store bought knifes but that's it) I have done all my research on steel type and since I am doing my own heat treating I'll be going with o1 but the metal supermarkets have it in flat stock and precision ground stock. Is it worth the extra money for precision ground? How much variance is in the flat or rectangular bar stock? Are the sides still flat or does it get that slight banana shape looking down the length the way cheap welding steel does? Thanks in advance for the advice

    I've used both and I prefer precision ground, just because thinner stock (3/32 - 1/8) tends to be straighter. Sometimes the standard stock has a noticeable bow in it. It's not a show stopper, just one more detail to manage in your build. When starting out, however, it can be worth a few dollars to start with a straight piece of steel. (All of which can be negated if the UPS guy stands on it in the back of the truck.)

    As for variances in thickness, my old eyes can't see any appreciable difference between precision ground and standard stock. You're going to be grinding or filing any piece of steel you use anyway, so I don't think it matters too much.

    Usually I get the mill finish and it's oversized to accommodate for finishing. The last piece of 1/8" mill finished S35VN I bought was about 0.138". Precision ground is usually within 1 thousandths (0.001") or better. This costs more as there is more work to be done before it gets to us. As I am going to effectively "precision grind" the steel anyway it doesn't make sense to buy precision or blanchard finished steel. Canadian Knifemaker Supply has O1 (what they call NOT GROUND or mill finish) for $2 an inch for 1/8" x 2". Metal Supermarkets offers 3 foot lengths and the last time I checked it was cheaper to pay the postage and get it from CKS. Will it the faces be parallel, for knife making purposes yes. As far as straight or not, you need to be able to tap it here or there to make it straight sometimes. That's a wonderful useful skill to have. You can tweak it as you wish before heat treat.
