These are some recent snaps of my 2 knives. Both are made by Camillus...the Mark 3 Trench knife is 23 years old and the USMC Fighting knife is going on 34 years old, though I think it is older since it was used in Vietnam by my uncle and I used when I was deployed. Last week I sand blasted the blades, then applied Brownells Matte Black Aluma-Hyde II Epoxy. Being so amateur at this, for those with an eye for detail, you'll see the lines near the edge aren't exactly straight. I also darkened the handles using Thompsons Watershield. I've used the fighting knife as my combat knife, regular camp and backpacking knife for about 11 years. The trench knife of course is pure combat, though used it as a spear to take a few fish when doing a survival course.
