False edges...

[Guy Thomas]

Do most of you guys grind in false edges before or after heat treating? I know some makers do it after heat treating but I'm a little hazy on why.

I do 98% of my grinding before HT. Got to love molten salt. The only reason I could think of doing it post HT would be to not chance any kind of stresses or stress risers in the blade during HT. I could see how grinding it in before HT could increase the risk of the tip warping/corkscrewing.

Grinding after heat treating eliminates almost all of the risk of warping. I grind the faults edge as well as the rest of the knife after heat treating. Grinding hard steel is easer to do accurately. Gib

Whoa!... Guy Thomas initiates a thread!!! Everybody duck! The sky is falling!

(Hmmm... I do only finishing after HT, all the other grinding is beforehand. A good normalizing sequence has eliminated problems with warping, at least as far as my eye and pool table slate (my poor man's surface plate) can tell.)

Sorry Guy, I just couldn't resist.

I usually do em about halfway prior to heat treat. Easier to even em up after its hardened, grinder doesn't get ahead so easy

 

[Kit Carson]

I'm with Gib on this one. I do all my grinding after heat treatment.
