Hardly! Heck, I buy a pack of razor cartridges AT LEAST once a year!
Wow Todd! Your friends are tough.
Next time you're here, I'll have to introduce you to a strop, a straight razor, a badger brush, and a shaving mug. A straight razor can easily last well over a century.
You just have to be a little careful using them. If you look up the history of the barber pole, it was a bloody rag wrapped around a white post.
Be careful shaving in the morning.
