Product Information
The Seac Rapid Daga is a dagger-blade stainless steel dive knife built for scuba diving, freediving and spearfishing, featuring a 10.5 cm (4.13 in) blade with a smooth edge on one side and a serrated edge along half of the opposite side, for a total length of 23.5 cm (9.25 in).
Who it is for
This knife suits scuba divers, freedivers and spearfishers who want a compact, dagger-shaped blade and a reliable way to signal a dive buddy. The small steel handle butt at the base doubles as a tank banger, letting a diver strike it against a cylinder to attract attention underwater.
Key details
- Blade: 10.5 cm (4.13 in), stainless steel, dagger profile, with a smooth edge on one side and a serrated edge for half the length on the other.
- Total length: 23.5 cm (9.25 in) including handle.
- Handle butt: steel, for making noise by striking the tank.
- Release: a button located near the handle attachment for quick removal from the scabbard.
- Scabbard: rigid, can be hooked on either side of the body and secured to a belt through two slots.
Rinse the knife and scabbard with fresh water and dry each piece separately with cloth or absorbent paper after every dive, even if the knife was only worn, since the scabbard is not watertight.
