## Overview

The SEAC Sharp is a premium spearfishing and diving knife featuring a 3.54-inch stainless steel dagger blade with a dual-edge design—smooth and serrated—for versatile cutting tasks. Its ambidextrous Double Release System allows quick, effortless access from either hand. Lightweight and compact at just over 8 inches total length, it includes two straps for secure mounting on the forearm or calf. Finished with a black protective coating, this durable knife is designed for professional apnea divers seeking reliable safety and performance.

## Description

Seac Sharp is an essential accessory for the safety of divers and of all apnea diving enthusiasts. The Seac Sharp diving knife has a "dagger" blade in stainless steel with a black protective coating, featuring a smooth side and a serrated side. The blade is 3. 54 inches long, while the whole knife measures 8. 07 inches. The handle is flat and has a practical symmetrical release system ("Double Release System") that makes it possible to unhook and fasten Seac Sharp to the scabbard with any hand and from both sides. Seac Sharp is supplied with two straps for fastening the diving knife on the calf or the forearm. Warning! It is recommended to always rinse with fresh water and to dry well with fabric or absorbent paper both the knife and the scabbard separately after each dive, even if the knife was only worn and not used, since the scabbard is not watertight.

Review: Best knife ever!!! - Really well-made and thought through knife! This knife is very exceptional! Locking mechanism works perfectly, the blade is EXTREMELY sharp, the size and weight is just right as well as durable, and last but not least it just looks good. I have not tried it in the water yet so I do not know how it holds up against corrosion but I would assume well as all the other features seem to prove this knife good quality. I have zero complaints!
Review: Perfect dive knife - Super easy to use and clip into my dive belt. Perfect size, not too big. High quality and sharp.

### ⭐⭐⭐⭐⭐ Best knife ever!!!

### ⭐⭐⭐⭐⭐ Perfect dive knife
*by S***A on August 22, 2025*

Super easy to use and clip into my dive belt. Perfect size, not too big. High quality and sharp.

### ⭐⭐⭐ I like the sheath system, but it has rust spots after a few dives.
*by R***A on January 7, 2026*

I bought this knife as a replacement for a knife I lost. That one never rusted. Even though I washed an oiled this knife, it developed rust spots quickly. The sheath system is great, though. Maybe you will be luckier than me.
