Perfect for the outdoorsman constantly needing to switch blade types and sharpen blades, True KnivesReplaceable Blade Knife has a 2-step locking system and comes prepackaged with three blade options: two 3.5-inch drop-point blades and one 3.5-inch saw blade. A blade-storage case is also included for the safe carry of extra blades while on the move. The 2-stage locking system is locked in place with the thumb stud, which slides back and forth for lock and unlock settings. The blade must be released via a lever in the spine of the knife once unlocked.
Despite being replaceable, each blade edge is made from 3CR13 stainless steel. 3CR13 is 0.3-percent carbon, 13-percent chromium and 0.6-percent nickel, along with other trace elements. This composition makes it highly corrosion-resistant while retaining a sharp edge for a longer period of time. Pairing the steel with a black oxide finish means that these blades can better handle extreme environments without showing signs of corrosion.
Black-fiberglass-filled nylon scales house the liner-lock system to keep the blade locked tightly in position. It is textured enough to add some measure of gripping surface without collecting particles. A small, deep-pocket carry clip is attached on the right-hand side for a tip-down right-handed carry. When opened, the Replaceable Blade Knife measures 8-inches overall, and closed it comes in at 4.5-inches. The knife is 0.75-inches thick, and from top-to-bottom measures in at an inch and a half. Replacement blade five-packs are available for $24.99.
