Thanks for posting this pic, Roger. Ok, here's the deal. This was one of the knives Burt submitted for his Mastersmith grading(which he passed; no surprise to anyone who has seen Burt's work).
Blade: around 10-11" of forged 52100. Ground nice and thin for such a big, honkin blade. Spine and underneath the ricasso mirror polished, while the flats are a really nice handrubbed satin finish.
Oval guard and ferrule: Damascus
Handle: one super sweet chunk of stabilized English Walnut with a single domed pin.
