Im looking at getting a single blade knife for my 4 groomsmen, and then getting the blade etched/engraved with their initials and the date of my wedding in it. Anybody got an idea of what a good size blade would be for a folding knife to get it to fit everything i want? I was thinking at least 2.5-3 inches. And im even open to the option of a fixed blade knife. Just trying to do something somewhat cost effective for me (so no the knives will not be high dollar) and not something everyone gets as a groomsmen. Any suggestions im all ears.
