The TUSA FK-910 / FK-920 X-Pert II is a professional-grade diving knife designed to provide dependable cutting performance, outstanding durability, and maximum safety underwater. Crafted from premium 420 stainless steel, this corrosion-resistant dive knife is built to withstand harsh marine environments while delivering reliable performance for recreational, technical, and professional diving.

The FK-910 model features a versatile drop point blade, ideal for a wide range of underwater cutting tasks. Both knife versions include a sharp straight edge, a serrated cutting edge, and an integrated line cutter, allowing divers to quickly cut rope, fishing line, webbing, kelp, and other underwater obstructions.

An ergonomically designed handle with an integrated counterweight provides excellent balance, a secure grip, and improved control, even when wearing thick dive gloves. This design enhances precision and handling in demanding underwater conditions.

For safe storage and rapid deployment, the knife is supplied with a durable sheath featuring a single-button locking mechanism that securely holds the blade while allowing fast, one-handed release when needed. The adjustable buckle and strap system enables comfortable attachment to the leg, arm, or dive gear.

The fully disassemblable construction makes routine cleaning and maintenance simple, helping extend the knife's lifespan and maintain optimal performance after repeated use in saltwater.

Worth the little extra it cost

Very nice knife. Good grip with real rubber and easy to take apart and clean. Extremely sharp blade. It's more purple than cobalt but I actually like it better purple.

Hard to put on

A little cumbersome to put on, not the most comfortable. But the knife seems high quality and o so sharp! Easy to remove and re-sheath.
