Ah........I was in the army from 69-72, vietnam 70-72, and I didn't get my 16 till early to mid 70. Went throught basic at the Knox with the 14. Maybe they where still being used in 1983 for training? I carrried m79 and 45, and a 870
I always.......with the Lindsays put a well defined flat on the top to index to. Also course grind allows to better orientate when cutting. parallel with the surface. I use rounds pretty much all the time
ah ........this sharpening situation...............I've been doing it since 2015 and am still learning. Actually one finds using a scope to examine all the intersections after polish helps a lot. Rob
