This may be the ultimate small knife, light, agile, reliable, easy to open, with a high degree of tactical form and function that echoes a Heckler & Koch heritage. The new HK30 Liner Lock features a 2.97'' recurve blade made of 440C high chromium stainless steel, chosen for durability and superior edge retention. Anchoring the blade is a black Zytel, nylon resin overlay handle, which simultaneously provides heavy texture on the bolster area and a scalloped pattern on the remainder, offering an enhanced grip.
