The Outdoor Edge Razor HTX is a multi-function replaceable-blade knife engineered for efficient field processing and utility use. A push-button blade change system allows rapid, tool-free swaps between 350 and 500 series blades, supporting 3.5 inch and 5.0 inch Japanese 420J2 stainless steel profiles including drop-point, boning, gutting, and a wood or bone saw. The black-oxide coated 420J2 stainless steel blade holder integrates a lock-back mechanism, while the SawSafe locking system secures the saw blade for controlled back-and-forth cutting without slipping. A full stainless steel frame is paired with an ergonomic orange ABS handle featuring a soft-touch gray TPR grip, a jimped spine, and an hourglass pivot for enhanced control in wet or slippery conditions. Overall length with a boning blade installed measures 11.5 inches, and the knife weighs 5.9 ounces with one blade installed. The folding design supports safe transport in the field and eliminates blade sharpening by using replaceable razor-sharp blades.
