Just like a katana you could cover the parts you would like to be softer.
I'd say use a lump of clay or jbweld before you heat and quench.

You might even get a nice hada
Although in a katana that is mostly due to different carbon contents values of the composite steels...

Ah yes..that's the word I was looking for...
It's been while since I last built a katana ( like 22 years.)
Like it, my japanese is a bit rusty..

Hada is "body"and I believe the hamon is the soul...so... :D

Funny mix up.

I know a little bit about it. I just gave a VERY brief synopsis. The key word is doing it "right". The heat treatment, whether it is standard or differentially treated, (to me) is dependent on what I want the knife to do. A lot of times, though, the differential heat treat isn't necessary on a file knife because of the spine. And by that, I mean the ENTIRE knife is a bit softer, say 50RC. If it's a smaller knife though, I tend to make it harder.

Now, there are a host of other factors that come into play as well, and they can play just as important a roll as the heat treatment. For example, the smaller knives I've built usually have a flat or scandi grind whereas the larger ones will have a convex, and that convex edge works pretty well with a softer edged knife.

See, look what you done. You done got me ramblin' on about something else. :D

"tell me what you think"

Not only can you stick/stab/cut something in self defense you can file them!

STOP! OR I'LL FILE YOU! LOL.

Looking pretty good, but how is it to hang onto?

you should give the handle a light coat of liquid electrical tape to make it a bit nicer to hold but not think enough to take the rough file marks out.
