Hi Brian, thanks!
Big smile, I am more and more leaving tools and jigs, rough and without finish. I have come to like the patina and that tools are made for use and abuse. But I agree shellac is kind of only right in amber, smiles. If I should do something to this one, it would be a dye and then an oil finish as I did with the workbench many years back (the bench were in such terrible state, that I had to). 
I'll thank you now for the comment. ;-)
