Spyderco Sustain Fixed Blade Knife CPM-20CV G-10 FB39GP
The Spyderco Sustain fixed blade knife is base on a custom design by Stuart Ackerman. The blade is CPM-20CV premium stainless steel, saber ground with a full tang. A large unsharpened edge on the spine reduces weight and helps to balance the knife and the handle is G-10. For easy carry in the field, the knife comes with a leather sheath.
