C4 Underwater Naifu Knives XLarge

The C4 Naifu Underwater knives feature an innovative and ergonomic design.They come in two sizes and two different types, with few differences amongst them. There is the polished, stainless steel blade version and the stainless steel, but white Teflon coated blade. This particular finish makes the blade more resistant to wear and reduces friction when to cutting. The blade is also easier to clean. Also the knives with a white and white blade make the knife extremely visible in case of loss in the bottom of the sea.

A very important feature on the C4 Naifu knives is that the blade is machined, to create a razor cutting edge, whose geometry greatly increases its cutting and penetrating effect.

The handle and the sheath are manufactured in recyclable POM material. This is a very sturdy and auto-lubricating material, with excellent mechanical properties and low water absorption. C4 has incorporated a sturdy locking system between the knife and the sheath, which makes extraction and insertion, easy.

The blade of the Naifu knives is inserted all the way in the handle, making it extremely sturdy.

Two basic differences between the Small and the XL size are:

• The XL size features a shaft remover
• The blade of the XL size comes out from the bottom of the handle, so it can be used as a light hammer

All knives, have one straight and one serrated edge.

The C4 Naifu diving knives are supplied with two rubber straps, with stainless steel buckles so they can be used, either on the arm, or leg.
