The blade for SAK 91 mm is made of M390 stainless steel, followed by cryo-heat treatment to a hardness of 61 HRC. The blades have a cutting edge at an angle of 30 degrees (15 degrees on each side).
ATTENTION! The blades have not been sharpened to razor sharp so you can safely install them on your SAK mod. And only after that, in the assembled state, make the final sharpening.
The blade is 2.3 mm thick, so they must be installed as a unit. On the reverse side, there is no way to install a small blade or bottle opener. The kit also comes with a special spacer (made of titanium) that is installed at the rear to balance the spring.
