Scottish Sgian Dubh Knife 

Differential Dubh @2008 Michael H. Mara

This Sgian Dubh has a 4 dagger point, convex ground, 440C blade, differentially hardened, with traditional spine grooves. The spine was coated with Satanite, a refractory clay, prior to hardening, towards achieving a hamon, or visible temper line. The spine is dead soft, while the edge is approximately HRC 62 ~ 65. The handle is antler with Nickel silver furniture and black vulcanized spacers. 8-1/2" OAL. Includes a hand tooled leather sheath, dyed to match the antler pattern. $413. SOLD

The hamon has proven to be a SOB to photograph on the finished knife. Shown below is a better picture.


And some pics of the sheath:
