ROCKSTEAD SAI-ZDP BLACK

The Sai is a beautiful piece of knifemaking for the collector or everyday carry user. Sai is Japanese for "Genius". This is a ZDP189 high carbon, powder metallurgic, stainless steel blade. With use of proprietary machines and nanotechnology, they’re able to get it to a hardness of approximately 67HRc. The exact hardness is tested on each model and will be noted on it’s certificate. Then that blade gets a mirror finish to not only look pretty, but also stay sharp longer, since surface imperfections can lead to nicks. The blade is ground in their ‘Honzukuri’ style, which applies a convex grind all over the blade, gradually getting a thinner angle towards the tip. It’s all full convex, without a micro bevel. Rockstead's inspiration for this is the Japanese sword. The handle is made of titanium, which has a black coating. It comes with a black leather sheath. The Sai has a total length of 190mm. The blade is 80mm, with a thickness of 3.7mm. It weighs 140 grams.
