My Dad had a beautiful razor sharp khuk he brought back from overseas. He kept it hanging on the wall with a crossed pair of original Sykes / Fairbairn fighting knives. The spine was at least 3/8" thick, and my Dad really knew how to sharpen a knife. It was the single sharpest thing I have ever held. It had a horn handle, and looking back I'm guessing it was 17" or 18". I last held it when I was a teenager, but I recall it was shaped like an AK, but had no fullers that I remember. The scabbard fit like a glove. I learned the correct way to draw a khuk from its scabbard when I was 12 and cut the living hell out of my hand pulling this knife from a tight scabbard incorrectly.
I loved that knife and my Dad used to let me hold it. Along with most of his guns, $20,000 worth of carpentry and mechanics hand and power tools, all of our shared freshwater and deep sea fishing gear and tackle, tents, backpacks and assorted camping gear, several knives he had made by hand, his expensive refracting telescope, AND most of a 3000 volume library with many first editions, it evaporated like magic within a few weeks after he died in 1982, sold off by his useless druggie POS stepson for coke and whores, and moron second wife. (Not that I'm still bitter after almost 25 years! (-
