The Spyderco Darn Dao faithfully translates every detail of Bob Lum’s meticulously crafted custom design into an equally dynamic production knife. Its satin-finished blade is full-flat ground from thick CPM 154 stainless steel—a state-of-the-art powder metallurgy stainless steel that offers increased toughness over the conventional ingot version of this alloy. For maximum strength and a deft balance, the gracefully curved blade has a tapered full tang that is flanked by contoured black G-10 scales. Like its historical inspiration, the Darn Dao’s handle flares at the pommel.
The Darn Dao comes complete with a handsome leather sheath with an integral loop for belt carry. The sheath’s open-backed construction and thumb-break-style snap ensure positive retention, while still allowing a swift draw.
