Columbia River Counterpart K431KKP 3.31" Folding Tanto Plain Black Oxide D2 Steel Black GRN

The Columbia River CRKT K431KKP Counterpart is a tactical EDC folding knife designed by Ken Onion around a purpose-built 3.31" tanto profile. The blade is forged from D2 tool steel and finished with a low-glare black oxide coating to deliver excellent edge retention and the piercing strength tanto blades are known for. A pair of ambidextrous thumb studs paired with an IKBS ball bearing pivot provides fast, smooth one-handed deployment, and the blade locks up solidly with an ambidextrous crossbar lock mechanism.

The handle is constructed from textured black glass-reinforced nylon (GRN) for a lightweight, secure grip that holds up to daily use. The blade carries a clean plain edge suited for both utility work and finer cutting tasks. An integrated pocket clip is included for convenient belt or pocket carry. The knife measures 5.6" overall when opened and weighs approximately 2.96 oz, combining CRKT's proven build quality with Ken Onion's signature ergonomic design in a compact, capable EDC platform.
