Cold Steel 4.5"e; Roach Belly Fixed Blade Knife Weight: 2.6 oz. Blade Thickness: 2.5mm Blade Length: 4-1/2"e; Blade Steel: German 4116 Stainless Cryo Quenched Handle Length/Material: 4"e; High Impact Polypropylene Overall Length: 8-1/2"e; Additional Features: Secure-Ex Sheath Knife Type: Fixed Blade Shape: Trailing Point Historically, the Roach-Bellied knife was a short blade with a pronounced upswept curve and a sharp point that saw popularity in 17th century Britain and the American Colonies. It was most likely named after the common Roach Fish, which had a similarly round curving belly. Cold Steels model is a nod to the Black Powder Community, which has continued to appreciate the Roach Bellys economy, versatility and effectiveness. The hollow ground blade is made of sub-zero quenched German 4116 Stainless steel, expertly heat treated to RC 56-57, and given a sharp edge that's easy to maintain. Instead of the traditional wood handle, ours is made of a tough injection molded polymer, making the Roach Belly considerably more weatherproof than historical examples - not swelling, shrinking, rotting or cracking like its wooden counterparts. The Roach Belly comes complete with a durable polymer sheath, making it a breeze to carry all day or on extended hunting or camping adventures.
