If you live in Eastern South Dakota, I can help you directly to keep your knifes and tools sharp. I need to keep my woodworking tools extremely sharp and I’ve got the tools to do it. These tools mean I can put a new sharp edge on your knifes and most other tools. My pricing will start at $5 per knife but it will depend on the amount of work needed to bring it back to razor sharp. If you want to ship your knives to me, contact me and we can figure something out.
