In 1970 I was getting ready to go back to Vietnam for my fourth tour and bought a Model 14 Stainless, from Van Sickle (?) a dealer in Texas that you could get the knife from right away with about a 25% mark up. I carried that Model 14 for the next 21 years, a tour in Vietnam, in the Philippines, Thailand, Okinawa, and the British Army Jungle warfare school in Brunei. I spent about 5 years on a Scuba Team (pre-Combat Diver) and swam it in salt water and fresh water, did 12 + Winter Warfare Exercises, at least one down to -40 degrees C/F, multiple parachute jumps, exercises in Germany and Italy and all over the USA. In 1988 I had custom knife maker Wayne Goddard, put a new handle on the knife as I never was completely satisfied with the finger grip handle it came with, carried it for three more years like that. I used that Model 14 to do whatever needed to be done, and it is still ready to go to the field. Not sure if that constitutes "Hard Use" but so what, it did it's job in the field for 21 years, so it was tough enough for me. John
