John’s tool is similar to the leather strops that old-school barbers use to sharpen straight edge razors. In the same way, Razor Renew can smooth the burrs and scratches on a disposable razor, bringing it back to like-new sharpness. What’s different is the material. John found that cowhide, which is great for straight edges, is too harsh for thin razor blades. He experimented with different leathers and different designs before settling on a two-sided combination: a suede side to sharpen and hone the metal, and a smooth leather side to buff and polish. The short version is for blades less than three inches long, and the long version works with larger knives, scissors, and other blades.
If you’re looking to get more use out of disposable razors, or you want a DIY tool to maintain your knives and scissors, Razor Renew is a handy solution. It’s made in the USA, and it’s designed to last a lifetime if you care for it properly. John wouldn’t have it any other way.
