Product Information
Seac Titanium Knife is a lightweight scuba diving knife built for divers who want a reliable cutting tool without extra weight on their rig. It pairs a 3.66 inch titanium blade, combining a smooth edge and a serrated edge, with a flat handle and a symmetrical "Double Release System," and the complete blade-and-handle package weighs just 3.52 oz and measures 8.26 in overall.
Who it is for
This knife suits scuba divers who want a compact, low-weight backup or primary cutting tool for line, net, or kelp entanglements. Because the Double Release System lets the knife be released and re-engaged with either hand and from either side, it works equally well for left-handed and right-handed divers. The flat handle profile and low weight suit divers looking for a very lightweight knife.

Frequently Asked Questions
Can both left-handed and right-handed divers use the Seac Titanium knife?
Yes. The knife uses a symmetrical, flat handle with a Double Release System, which lets a diver release and re-engage the knife with either hand and from either side of the scabbard, so it works the same way for left-handed and right-handed divers.
Where is the Seac Titanium knife meant to be mounted?
It comes with two straps that let you fasten the scabbard to either your calf or your forearm, so you can choose the mounting location that best fits your exposure suit and gear configuration.
Does the Seac Titanium knife include a sheath?
Yes. It ships with a scabbard along with two straps for mounting it to the calf or forearm. The scabbard is not watertight, so it should be rinsed and dried separately from the knife after every dive.
How should I care for the Seac Titanium knife after diving?
Rinse the knife and the scabbard separately with fresh water after every dive, even if the knife was only worn and not used, then dry both well with fabric or absorbent paper, since the scabbard is not watertight and can trap moisture.
