Jewelers have a special holding tool for almost each purpose. There are ones for holding rings while setting stones. Ones for holding rings while polishing...while engraving...while assembling heads to the ring...etc. Then there are pin vises in many sizes....and watch makers vises to hold different case shapes...and to hold movements...and crystals. There are many different hand vises to hold small parts while setting stones and making parts.....And a couple of small bench vises for general vise jobs.
The GRS benchmate system is basically a bunch of different vise and holding tools that all fit a universal mount on your bench front.
On the subject of tools, we are getting ready to move the store into a new ,and larger, store space. I will have a dedicated workroom and a separate polishing room. The workroom will have many jewelers benches ,and I will bring all my specialized tools there. When the move is done, I'll post photos of the work space.
