The Columbia CR5570 comes with a 2.30” modified spear point blade that is made out of 420J2 stainless steel. Has a non reflective bead blast finish and notched thumb rest which provides a more secure grip.
The handle is bead blasted stainless steel, with a single black zytel scale and an internal frame lock (a locking mechanism in which the liner is actually part of the handle rather than a metal liner distinct from the handle).
Comes with thumb studs that allows the knife to be opened one handed with no effort needed at all, which comes in handy if your other hand is otherwise busy.
