Product Information

The Seac Rapid is a stainless steel dive knife built for scuba diving, freediving and spearfishing, with a 4.13 inch blade that pairs a smooth edge with a serrated section covering half its length, for a total knife length of 9.05 inches.

Who it is for

The Seac Rapid suits divers, freedivers and spearfishers who want one knife that can cut line, cordage or netting with the smooth edge and saw through tougher material with the serrated section. The small steel handle butt doubles as a signaling tool, letting a diver rap it against a tank to get a buddy's attention underwater.

Key details

Blade length: 4.13 inches, stainless steel, with a smooth edge on one side and a serrated edge for half the length on the other.
Total length: 9.05 inches.
Steel handle butt at the base for making noise against a tank.
Release button located near the handle attachment.
Rigid scabbard that allows the knife to be hooked on both sides.

Compatibility and sizing

The Rapid is built for scuba diving, freediving and spearfishing use. The scabbard has two slots for belt mounting and comes with two straps for securing it to an arm or calf, so it can be worn in the position a diver prefers. The scabbard is not watertight, so Seac recommends rinsing the knife and scabbard separately in fresh water and drying both thoroughly after every dive, even if the knife was only worn.

Frequently Asked Questions

What edge does the Seac Rapid knife have?

The Seac Rapid has a 4.13 inch stainless steel blade with a smooth edge on one side and a serrated edge covering half the length on the other side. This combination lets a diver cut line or webbing cleanly with the smooth edge and saw through tougher material with the serrated section.

How do you attach the Seac Rapid knife underwater?

Is the Seac Rapid knife scabbard watertight?

No, the scabbard is not watertight. Seac recommends rinsing the knife and scabbard separately in fresh water and drying both thoroughly with fabric or absorbent paper after every dive, even on dives where the knife was only worn and not used.

Is the Seac Rapid knife suitable for spearfishing?

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.

New to this hanger...Now I'm a believer

Used tons of dive hangers, but never an upside down hanger. Game-changer for me. Will now add more of these in the near-future.

With it's swivel head design, it can cram itself into my tight dive locker, while still donning a ton of gear.

DiveCatalog's "Upside Down Drysuit Hanger w/ Regulator and Accessory Hooks" is a great product with solid construction at an affordable price. All of that with Dive Catalog's customer support/satisfaction guarantee.
