The KS1475 Ken Onion Storm II knife, by Kershaw knives. Looks and acts incredible. Performs even better.
It's got a super sharp 3 5/8th inch pure cutting blade made using Sandvik 13C26 stainless steel. With a simple thumb push or index-finger flick, the blade recoils into the stainless steel handle, complete with trac-tec inserts, which offer an incredibly superb level of grip.
It weighs in at 5.6 oz, is incredibly agile and perhaps one the very best looking, most useful knives around today. Definitely one to add to your collection.
