The brand-new M-21 is the fusion of two classic knives of CRKT. M-18 and M-16 have been merged. The demand for a slightly bellied blade for every-day use got louder and louder. The ergonomic design of the handle of the M-16-series is well proven a thousand times and more. So why not combine both models? The result is quite convincing. The modified blade of the M-18 is ideal for cutting, carving, and peeling. The additional LAWKS safety prevents the stainless AUS-8 blade from closing accidentally. With the Carson flipper the knife can be opened fast as lightning. Plain edge.
