- Form and function in the same package. The first variant in the Freek family brings together two incredibly durable materials, G10 and CPM-M4 steel. The gray and black layered G10 is milled to provide excellent grip and style, while the red G10 base layer and anodized aluminum barrel spacers bring an additional pop of color to the handles. The high-strength CPM-M4 blade is designed for hard use, pushing the limits of what the already tough Freek was meant to do. This knife is a true super Freek.
