The Spyderco® Endura folding blade is an excellent hard-use knife by virtue of its heft and solidity. It also offers a surface for custom engraving and Embellishment. The C10 Endura has a modified skinning-style blade, laser cut out of AUS-6 high carbon steel. Two sets of pre-drilled holes allow the metal clip to be positioned for a tip up or tip down carry. The blade is hollow ground.
