I have a Brett Dowell M4 blade at 65 Rc that is a cutting sumbuck. It's a high hollow grind and ground thin on a B&T pattern. Brett put an acid etch on it and so far no problem with freckling. The acid etch is just turning from black to a nice gun metal grey. Probably my favorite fixed blade.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
