Long but slender, the Frenzy II from Cold Steel is among the largest folding knives available that are still easy to carry. It boasts a 5.5" powder-steel blade—with a thick spine and straight cutting edge—Cold Steel’s reliable Tri-Ad Lock and trim, sculpted black-and-blue G10 grip panels. The Frenzy II is certainly a formidable back-lock folder. Yet, despite being nearly 7" long folded (12.25" open), the knife is still easy to pocket thanks to its trim design and sub-6-oz. weight. Price: $240. Contact: Cold Steel; (800) 255-4716; coldsteel.com.
