not especially sophisticated and won't replace any of your special or custom knives. But if you want something that is in fact handy for cutting things, this is it. The blade is about 4 inches, made of some kind of really stainless steel. Thin and very sharp blade. Plastic handle with knurled grip. The neat part is the plastic sheath that slides on to the blade and stays put. Same stuff as the handle. When you slide it on the blade it's a one piece affair, sort of like the samurai swords and knives. About 7 1/2 inches with the sheath on. You can throw one in your pocket or your day pack without fear of cutting anything which is the case with kitchen knives. Mine's about 25 years old. Used to use it for hiking, but has resided in my office desk drawer for the last dozen years or so. Use it every day for cutting oranges, spreading spreads, cutting open envelopes and packages. Everything. Rinsing it off in the water fountain is all it needs. I've never sharpened it. Doesn't need it. Available for $8.35:
