Ok guys, I know I sound like a dumb A__ but I have a question. I have a Buck119, TAK1095, Hen and Rooster bowie (German Soligan Steel), Old Camillus KBar, Ontario pilots survival knife 1095, and a few other sheath knives. Those are my main ones that i like. The question is. What is Hollow ground mean and Flat ground. I dont understand that stuff. Especially hollow ground on my Buck119? Thanks for the help.
