A Grey Blade

I made this knife about a year ago.  It's another case of an accidental hamon from differential hardening - only part of the blade was above the critical temperature to form truly hard steel.

The lighter colored section toward the back of the blade is softer than the rest of the blade.  I left the blade etched grey like this because I thought the patterns in it were really interesting.

The blade is 8" long and made from 1/4" thick 1075.  The fittings are 416 stainless steel, and the handle is carved micarta (resin & paper).
