I was taken by the crispness of the bevel lines & neatness of the plunge line. The execution of the file work is exceptional to my untrained eye. I like the way you filled the filed away portions with resin and worked it off.
It took me a while to assimilate the detail of the filing jig. I have never seen such an elaborate jig with such intricate mechanisms in it. I am impressed to say the least. .
