Clark,
One thing that may help you keep your new borer sharp is to place it back together correctly. Too many peope put the borer back together by dropping the borer into the hollow handle. That will dull the tip pretty quickly. When you put the borer into the handle, tip the closed end of the handle up and push the borer into the handle using the extractor tray to put it all together. That'll keep the tip from dropping into the handle and keep you from losing any of the parts. Keeping a new increment borer sharp from the get go is a lot easier than having to sharpen one later on. Good luck with your project.
