Reload your RazorSafe folder with the Outdoor Edge 3.0 inch drop-point combo pack. Four replacement blades drop into any 300-code RazorSafe knife in seconds, with no sharpening, no stones, and no guessing whether the edge is still honest. Keep a pack in the truck, the range bag, and the hunting pack so a dull blade never ends the job early. Each blade is Japanese 420J2 stainless, heat treated and hand finished to a shaving-sharp edge before it ever leaves the factory. The pack splits four ways: two plain edge drop points for clean slicing and portioning, and two 50 percent serrated drop points for rope, webbing, and anything fibrous that a straight edge would skate across. The blade code stamped on the pack is 300, which is the only number you need when restocking, and it covers the 3.0 inch RazorSafe knives that carry the same code. Blades seat and lock with a push of the release button, so a swap takes longer to unwrap than it does to install. Cheap, sharp, and disposable in the best sense, this is the refill that keeps a replaceable-blade knife worth carrying.
