Richmond Laser 150mm Petty. Introducing the Richmond Laser. Many thin knives have been nicknamed "Lasers" over the years and they've been popular on our site. I thought I would take a shot at my own laser using my favorite stainless steel, AEB-L and heat treat them to my specifications at 61 Rockwell and add a nice upgraded octagonal handle made from bubinga wood and wenge ferrule. The result is one of the best performing stainless knives that I've tried and I hope you like it as much as I do.
