Repurposed. Leitz Summicron 50mm DR

A couple of weeks ago, I Blipped a sample which I made up some years ago as an experiment for drawer fronts.  It proved too labor-intensive to be viable at the time, so I found another, easier solution.  But the sample has been sitting on my bench as I've considered what to do with it.  Since one of the most indispensable tools in a woodworker's kit is an accurate square, I decided to repurpose the sample as a holder for two of my favorites. They now hang on the wall just above my bench, within easy reach.
