This is a less expensive titanium knife from ProMate, called the Seal. It’s less expensive because it’s from a low-profile maker and it’s a folding knife.
It’s give-and-take. On one hand you’d have the strength of a titanium blade in a compact package in your favor. But on the other hand, you’d have less strength and durability since it’s not a full-tang blade, and you may not want to deal with the inconvenience of having to open your knife while underwater.
The Seal sure has one tough blade, though. The titanium blade measures 3.5 inches, and features a lot of different edges for water-related tasks. You’ll find a partially serrated edge, an extremely sharp tip, and a deep frontal gut hook along the top edge.
Another handy feature is the attached lanyard on the lightweight handle. It’s adjustable too, so you can affix it to just about anything you’ve got on and you’re good to go.
No question about it, this is a decent little underwater utility knife that comes in a convenient lightweight package. However, if you like your titanium blades fixed, then check out ProMate’s titanium Barracuda. Or upgrade to a more-serious, and more expensive, dive knife from Underwater Kinetics.
