The Spyderco Endura 4 CPM SPY27 Lightweight (brand part no. C10PCBL) is a 3.8-inch folding knife that brings Spyderco’s proprietary SPY27 blade steel to one of the brand’s most iconic lightweight models. CPM SPY27 was developed with Crucible Industries to take the time-tested performance of cobalt-enriched VG-10 and supercharge it with niobium, nitrogen, and increased volumes of carbon, molybdenum, and vanadium, resulting in a purpose-built steel with an exceptional balance of edge retention, toughness, and corrosion resistance. Made in Japan, this Endura 4 keeps all the features that made the standard version a favorite for hunting, camping, and daily carry while stepping up the blade material for users who want more performance from a familiar design.
