Nautilus Alpha

Regular price $345.00 $0.00

The Nautilus Alpha is an all purpose solid one-piece fixed blade knife design, dialed towards maritime use conditions, and features our Terravantium™ blade alloy that we guarantee is impervious to rust in all natural elements. Sitting at a mid-size OAL of 8.50", the Nautilus Alpha is a performer in, around, and under salt or fresh water environments.  

Rust-proof, stout, with a 3D contoured handle specially coated in a textured-colored epoxy, and excellent edge retention. A unique, modern industrial casting process forms our specially formulated, rust-proof, alloy blades. From diving, boating, portaging, fishing in Bristol Bay, or navigating through an uncharted jungle track in your rig, the Nautilus Alpha is an all-around cutting tool for explorers and adventurers who find themselves in and around a lot of water. Available in the colors shown.

We recommend a fresh water rinse after any immersion in salt water to properly maintain the eyelets and hardware used in the Kydex sheath.
