Fällkniven is very ‘modest’ about the S1. They think it's the best hunting and fishing knife there is. And maybe they’re right too! The blade is made out of very strong laminated VG10 steel. Its sharpened convex making the knife edge really strong without increasing the risk of chipping. The blade has a modified clip-point shape by which the S1 creates high penetrating power. Although it is not a very large knife, it is big and strong enough to chop with. This makes the Fällkniven S1 very suitable for survival.
The blade runs through the Thermorun grip which makes it full-tang. Fällkniven chooses Thermorun because it offers great grip even when cold, wet or in other poor conditions.
This version of the S1 comes with a left-handed Zytel sheath. A thin sheath with an opening on the bottom to drain moisture. And left-handed which is much easier for left-handed users!
