Useful in a wide variety of situations from camping to self defense, an outstanding knife belongs in every man's toolkit. The Kershaw Ken Onion Red Blur Folding Knife ($55) fits the bill nicely. Measuring only 4.5-inches when closed, the Kershaw features a 3-3/8-inch 440A stainless steel blade with a "SpeedSafe" design. Although it's not a switchblade (which is illegal in most places), it works very much like one. Push the thumb-stud on the blade past the handle, and the torsion bar takes over, springing the knife open smoothly where it locks into position. The handle is made of red anodized aluminum with Trac-Tec. There's a completely black model ($54) as well as a Tactical version ($60) which features a partially serrated Tanto blade. Just be careful peeling that apple.
When it comes to handy and safe pocket knives, the Buck Redpoint Knife ($36) is at the top of the list. Continuing Buck's 100+ year legacy of knife-making, the Redpoint has it all, from the SafeSpin technology which allows easy one-handed opening and closing of the knife without touching the blade to the durable grip that makes for better usability in any weather conditions.
