Review: Good build quality - I was impressed with this knife. It comes with its own sheath that has a button release for safety. It has rubber straps to attach to your arm or leg. I don’t use this for diving so can’t comment on but it does have a weight at the bottom of the handle. I use this for kayaking where I use an anchor so keep it close just for safety. The blade is sharp and decent quality.
Review: Using as a safety knife for sailing - Bought this as a friend also had one and it seemed a good piece of kit. Knife has a good heft and is sharp enough for everyday use. Fits into sheath with a positive click and is secure even upside down. Easy to release when needed. Straps are a bit fiddly to adjust but seem sound. Plastic clips seem ok and I have them strapped around the steering column on a boat. As a diving knife I don't expect any issues with water/salt and unlike some safety knives which have leather sheaths the only maintenance this seems to need is a quick rinse in fresh water (I'm a bit over cautions so I also wipe down the blade with an oily cloth after rinsing). So far have been very happy with it.

## Features

- Stainless steel bunch essential to attract the attention of the companions during a diving: simply pull out the Seac Hammer knife from the sheath and beat the end of the handle on the cylinder
- ANTI-SLIP GRIP: The rigid body of the Seac Hammer diving knife handle features a soft rubber overprint that increases grip for added safety, both with gloves and bare hands
- REVERSIBLE FIXING: Seac Hammer Diving Dagger sheath attaches with two practical straps provided and allows you to safely store the knife by inserting it indifferently on both sides
- 12 cm tempered stainless steel blade and a total length of 25 cm; the Seac Hammer underwater knife can be hooked with a slash, thanks to the practical eyelet for added safety
- APNEA FISHING: In addition to being one of the diving accessories, Seac Hammer is also a great knife for apnea fishing

### ⭐⭐⭐⭐⭐ 420 Stainless Steel blade.
*by M***N on 18 November 2025*

This knife is made from 420 stainless steel from my findings. I really like it and it is cheap. I struggle to sharpen stainless steel knifes in all honesty. I have tried many ways. Next I am buying a diamond stone basic machine that clamps the knife in place and runs the diamond stone along the edge at any given angle. I will go for 20 degrees probably. 420 stainless . This below is copied and pasted 420 stainless steel is harder, more wear-resistant, and heat-treatable, making it ideal for knives and tools, while 304 stainless steel offers superior corrosion resistance, weldability, and is non-magnetic, making it suitable for food-grade applications and medical equipment. The main difference is their intended use: 420 prioritizes strength and sharpness, while 304 prioritizes durability in corrosive environments.
