The Spyderco Tenacious has been one of Spyderco's most successful budget offerings since its introduction. The black stainless steel blade variant adds a tactical aesthetic to an already capable worker.
The Tenacious uses 8Cr13MoV steel — a Chinese stainless that Spyderco specifies with tighter heat treatment standards than most production houses. This results in a blade that takes a finer edge and holds it longer than you'd typically expect from this steel grade.
The blade geometry is where the Tenacious truly excels. Its full-flat grind from the spine to the edge creates exceptional slicing geometry — an unusual feature at this price point. Most budget knives use hollow grinds or sabre grinds that compromise cutting performance.
The G10 handle scales are textured well and provide a secure grip in wet conditions. The back lock mechanism is solid and doesn't show blade play even after extended use.
At under $40, the Spyderco Tenacious in the black blade variant delivers a full-flat ground blade, G10 scales, and Spyderco's legendary ergonomic design — making it our top recommendation for budget EDC shoppers.
