Main advantages of the Undercurrent knife

🧷 1. Excellent CPM MagnaCut steel

This steel combines extreme corrosion resistance, high toughness, and edge retention. It is ideal for harsh conditions—especially in saltwater environments where ordinary steels corrode quickly.

🔪 2. Partially serrated edge

The combination of a plain edge and serrated section allows for fast and efficient cutting of rope, netting, and fibrous materials, while also enabling more precise cuts when preparing fish or bait.

🤲 3. Santoprene handle

The soft, rubberized Santoprene material is slip-resistant even when wet or when handling the knife with gloves. Its ergonomic shape ensures a comfortable and secure grip.

🛡️ 4. Practical sheath

It comes with a sturdy plastic sheath with a snap closure that securely holds the knife in place. Thanks to multiple mounting options, it can be worn on a belt, attached to a backpack, or mounted directly on a boat deck.
