I used my new Dewalt coffee grinder for the first time last weekend. Modified a set of commercial snow chains to fit my smaller farm tractor. If you're familiar with duet chains then you know that you usually can't just shorten them, it's almost like reengineering. Cut 6 links on each chain to fit and the grinder was a lot easier than pulling an extension cord and electric grinder. Also, I can sharpen my lawn mower blades without removing them, which saves a lot of time. Very convenient. There will be many more applications, I'm sure.
