I recently returned to using double-edged razors for shaving. Many interested in vintage razors and wet shaving have collections of razors and different blades. How do you keep track of how many shaves are on each blade? One razor and one brand of razor blade aren’t too difficult to keep track of when I last changed blades. But with multiple razors and many different blades, it can be challenging to keep track.
I’ve made a blade tracker using a guitar volume/tone knob to keep track of my blade use. To read more, see my blog site (dansissors.com) post, How to make a Guitarist’s razor blade use tracker.
