Frequently Asked Questions

What are the primary uses for the TUSA FK-940 "Expert II" Titanium Dive Knife?

The TUSA FK-940 is primarily used as a tool for divers to cut lines, free themselves from kelp or fishing gear, and for general prying tasks underwater. It can also serve as a last-resort defensive tool against marine life.

What makes the TUSA FK-940 suitable for saltwater environments?

Its blade is made of titanium, which is highly resistant to corrosion and rust, unlike many stainless steel knives that degrade in saltwater. This makes it ideal for repeated use in the ocean with minimal maintenance.

How does the TUSA FK-940 compare in size to other knives?

The TUSA FK-940 has a 4.5-inch cutting surface and an overall length of about 9.75 inches. It is shown to be similar in size to a Spyderco Endura folding knife, which is considered a larger folding knife.

What are the potential drawbacks of the TUSA FK-940 dive knife?

The handle grip is considered somewhat small by the reviewer, and the blade length might be insufficient for very dense kelp. The initial edge out of the sheath is also noted as being rough and requiring sharpening.

Can the TUSA FK-940 be used as a tactical or LBE knife?

Yes, its lightweight design, secure sheath, and corrosion resistance make it a viable option for Load Bearing Equipment (LBE) or tactical use, with potential for adaptation to MOLLE systems.
