Thread: Twinplex

I had always wondered if this thing really works or if it was just a gimmick.well today I seen one while i was antiquing and decided to pick it up. so I got home picked out a new razor blade and sharpied the bevel of the blade. Threw it on the twinplex and tried. 20 seconds later, i looked at the bevel of the blade. It was shiny and brand new. It has to work. That's how i check my straight razor bevel. If marker goes away on hone bevel is set
