Highly Textured Ti Handle, S35VN Blade

Designed by Danish custom knifemaker Mikkel Willumsen, the Yamakasi features his signature urban tactical aesthetic. Right up front you’ll notice the striking handle, which is made from 6AL4V titanium. Donning a scaled pattern of grooves, it’s very grippy for security in slippery conditions. The blade is made from CPM-S35VN steel, widely regarded as one of the best commercial steels on the market for its edge retention and wear resistance. It has a compound grind for strength at the tip and precision everywhere else. Deploy the blade with the flipper tab and it will lock via the titanium frame. A tip-up clip provides easy carry for righties.

Note: This drop is limited to 100 units. Due to the sensitive nature of shipping knives internationally, we are able to ship only some of the knives on Massdrop to select countries. It is the responsibility of the buyer to know and comply with all importation regulations and local laws. Click here for additional information.
