Smoker's Tools

I just got this nice little smoker's tool corkscrew. It has mother of pearl scales and is used for opening cigar boxes among other things.

I already had one of these with ebony scales. The ebony version is much larger. Both are marked D.R.G.M. on the hammer which means that it is a German patent. The mother of pearl version is marked No 42057 whereas the ebony version is not.
