NAIFU features an innovative and ergonomic design. NAIFU is a belt knife with a total length of 204mm and a blade length of 94mm.
I purchased this as a back-up knife however it's already taken the place of my main fish dispatcher. Very solid build and is easy to handle underwater. The sheath clip is solid but allows easy access. Great little knife.
This knife is not only suitable for spearfishing but all types of fishing, It can be strapped onto the arm, waist and legs, the design allows the knife to slide into the sheath with ease and the handle will stay secure, overall it is a very good knife to have.
