John Carmona

Owner and Lead Sharpening Specialist

When I'm not working on forts or pranking my employees, I like to spend time building a sharpening business. I started Sharpening Supplies in 2006 because I enjoyed cooking and woodworking, two hobbies that both depend on sharp edges. The problem was that good information and quality sharpening equipment were surprisingly difficult to find. Nowhere offered a real selection, quality tools, and expert guidance in one place. So I built it.

In the last 20 years, I've learned far more about sharpening than I ever imagined possible. But I'm still learning every day. The more I learn, the more I realize how much more there is to learn.

Hobbies: Woodworking, Cooking, Fishing, Running

I've found that keeping a record of my knife sharpening helps me become a better sharpener.

Here is a fun fact: my first real sharpener was the DMT 6” Diamond Whetstone in fine grit. You could say it helped kick off my love of sharpening.

The Edge-On-Up Sharpness testers are one of the best ways to improve your sharpening. I use it while sharpening to verify my results.
