HB-301 is the blade from the Helle Temagami. The sharpened portion is about 4" long, 1 1/16" wide and .121" thick. Including the tang, it's just 9" overall, done in satin polished laminated carbon. The rivet holes are about .20" in diameter, the thong hole is about .25" in diameter. This would make a seriously stout wilderness or utility knife.
