Columbia River Helical 3.52" Tanto D2 Black Aluminum Folding Knife

The CRKT Helical is a hard-working tactical folding knife built around a tough D2 tool steel blade with a striking tanto profile and a protective black oxide finish. At 3.52 inches of blade length and an 8.13 inch overall length, the Helical is sized for serious everyday carry while still feeling comfortable in the hand during heavier cutting tasks.

The blade deploys via a flipper opening system and locks up with a sturdy liner lock, giving the knife reliable lockup and quick one-handed operation. The handle is precision-machined from 6061-T6 aluminum with a black finish, providing solid grip security, corrosion resistance, and long-term durability. At just 3.6 ounces, the Helical carries light without feeling insubstantial.

D2 tool steel is a high-carbon, high-chromium air-hardening steel prized for its excellent edge retention and wear resistance, making it a smart choice for a hard-use EDC blade. The tanto geometry adds tip strength for piercing and detail work, while the plain edge delivers clean, controlled cuts on rope, cardboard, and everyday materials.

Designed for EDC and tactical use, the Helical ships complete with a pocket clip for secure everyday carry. With a closed length of 4.58 inches, it sits comfortably in the pocket and rides ready for whatever the day brings. Whether you are opening packages, tackling outdoor tasks, or adding a reliable blade to your kit, the Columbia River Helical delivers performance that punches well above its price point.
