    This Knife features an OutBurst mechanism that instantly springs the blade fully open after you have opened the blade approximately 30 degrees. M4 models have dual thumb studs for ambidextrous one-hand opening and bronze bearings and lubrous washers at the adjustable blade pivot for smooth, fast action.

    The 3.25" blade is a high-hollow-grind drop point of premium 8Cr13MoV stainless steel in a bead-blast finish with a Razor-Sharp edge.

    The heavy-duty InterFrame build is true to design, with dual stainless steel liners, one locking, and a stainless steel back spacer.

    The M4-02S Stag is a deluxe model which has a traditional look with stag scales and brushed stainless steel bolsters, plus our LAWKS safety.

    All M4 models have high-mounted pocket/gear clips.

    So here you have a friendly E.D.C. knife that fits the hand naturally for all kinds of cutting and carving tasks. Like Kit, it's a bit unassuming, but it's a knife you'll come back to year after year.
