Welcome to Dive Gear Reviews, a comprehensive guide to scuba diving equipment. Scuba diving is an expensive pursuit, so looking up reviews for a particular article of equipment is a wise precaution before investing any hard-earned money in it. However, consumer reviews may or may not be written by an experienced diver, and magazine reviews could be suspect due to the advertising ties of the publication in question. Dive Gear Reviews provides cross-referenced reviews assembled by an expert, making it possible to see at a glance what multiple sources said about a particular piece of scuba equipment. If one magazine loved a scuba regulator or a dive computer, but the consumers hated it, that information will be found here.

Tusa FK-850 X-Pert Dive Knife Review

Written by Dive Gear Reviews Editor. Comments Off on Tusa FK-850 X-Pert Dive Knife Review Posted in: Below $100, Dive Knives

Tusa’s FK-850 is a no-nonsense knife. The blade is 4.5 inches long and has a standard edge on one side, a serrated edge on the other, a cutting notch below the serrated edge, and deadly point on the end. Made from 420 stainless steel, the FK-850 is can be wickedly sharp and hold an edge well, but like all stainless steel blades, the knife is not truly rust-proof. Saltwater makes even the highest quality carbon-based stainless steel rust without proper car. So, in addition to vigilantly dunking this knife in freshwater after each dive, a diver should coat the blade with a few drops of machine oil for extra corrosion resistance as part of his regular maintenance routine.

The overall length of the blade is 9 inches, and it has a simple plastic handle with a textured rubberized grip pad at the index finger/thumb spot. The knife fits into a hard plastic sheath with a button release. Some dive knife locks using a one-push button release mechanism tend to be insecure, but Dive Gear Reviews did not find any consumer complaints about the locking mechanism of Tusa’s X-Pert knife as part of its standard research. Instead, there were glowing reports about the FK-850’s sharpness, ease of handling and general toughness from spearfishermen.

Perhaps the best part about this knife is how the price has come down since it was first introduced. Originally marketed at $55, the Tusa FK-850 X-Pert is now generally available for around $30. That price is so cheap that no diver has an excuse for not owning a proper dive knife.

Average Price: $30
