We went to WalMart to get some stuff. As we were leaving, I spied this key making machine. I didn't try it. It strikes me that it might work well. My guess is that WalMart at this location didn't have a key making capability. Adding this machine is one more thing that people can come here for. Something for everybody.
I always liked watching keys getting cut at the hardware store. The sound of the cutter is unmistakable. Most of the time they worked when we got them home and tried them. It is one of those Americana things like the long departed tube testers.
