Cutting Edge
The Spyderco Sage 5 featuring CPM REX 121 steel is a cutting-edge release that highlights the exceptional performance of one of the most advanced tool steels available today.

When applied to knives, it offers extreme levels of edge retention.
This example is in pristine, like new condition. Complete with original box and papers.
