Technical Specs

Spyderco Sage 4

The Sage 4 emulates the elegant simplicity and meticulous craftsmanship that characterized Al Mar's original designs. The handle is built on a framework of full stainless steel liners for strength and rigidity and reinforced by satin-finished titanium bolsters. The bolsters are carefully mated to scales machined from genuine Arizona ironwood and all components are assembled with contrasting black-coated Torx screws.

Like all knives in the Sage Series, the blade of the Sage 4 is full-flat ground from premium US-made CPM S30V stainless steel. Its leaf-shaped profile is distinctive to Spyderco knives and provides an excellent balance of cutting performance and tip utility that makes it ideally suited to virtually any task.

The blade and handle of the Sage 4 are joined by the front lock mechanism developed by McBurnette and his peers and popularized by Mar. When combined with Spyderco?s Trademark Round Hole in the blade and a reversible wire clip that supports left or right-side tip-up carry, the result is an exceptionally evolved folding knife that can be easily opened and closed with either hand.

The purpose of the Sage Series is to acknowledge the contributions of innovative knifemakers and give credit where credit is due. We hope you agree that the Sage 4 accomplishes this in style and sincerely hope your knife serves you well.
