I have recently been practicing some sharpening techniques that I picked up from Carl Swensson, a great Baltimore area woodworker. After spending hours sharpening my chisels, I found myself looking for a way to protect the edges from nicks and chips while transporting them, and also wanted to protect myself from the very sharp tools, since I recently lost a chunk of my index finger to a freshly sharpened blade.

After some searching, I found a great article by Chris Schwarz about using Plasti Dip and masking tape to make edge guards. I was unable to get the snug fit I was looking for using his method, and the Plasti Dip was nasty to work with. Fortunately, I noticed that low-temperature hand-moldable plastic was recently added to the Adafruit shop, and decided to give it a try. The results were exactly what I was looking for, and the process couldn't be simpler. Let's get started.
