ScubaproX-Cut Titanium TEK Knife with Nylon Sheath 5 in.

Yep it is old 5 inches long overall and will only fit in the smallest of hands. Hard to put an edge on the blade also.

A handy, zero maintenance knife. I use it for freediving - I rarely (pretty much never) need a knife, but it is critical safety equipment. The knife, while small, is well designed. It's also easy to wrap paracord or somethingon the handle if you want to fill it out a bit.Titanium is a lousy knife material. Contrary to popular belief - it is soft, quickly loses it's edge and will not take a fine edge. That said - it can easily be made reasonably sharp (which is as good as it gets) and will not rust. Good low-use safety knife. Plan to sharpen it after every use.
