Finishing up a blade,

and this one I decided to parkerize.

Which, if you're not familiar with it, is a phosphate coating chemically deposited on the metal surface to help prevent rust. A few years back I got a bottle of a concentrate for treating knives and I've still got the solution I mixed up; some are only good for one use, this stuff you can keep using. Nice and simple to use, just bring the solution up to 165-180F(and it's not real sensitive, you can be a bit lower and it'll still work) and hang the clean, degreased steel in. After about twenty minutes, take it out and let it dry completely, then oil.

Here's before:














This one was forged out of a harrow tooth, and the guard is hammered brass soldered into place on the tang. That's a 400-grit finish, which is as fine as I usually polish unless special request/need. So into the bath for 25 minutes, and here's after:

















You'll notice a difference in color between the edge and back. Remember the differential hardening I wrote of before? It causes that, the stuff grabs just fine but looks different on the different hardnesses.

It doesn't actually stick to the brass but it does discolor it. A little careful polishing with a dremel and a polishing wheel will take care of that. Then fit a grip and pommel.
