Made from steel, this solid triblet should be kept clean
and polished as any marks will be transferred to the
metal's surface.
Used to form or reshape and aid in the sizing of rings -
(by tapping the shank carefully with a hammer).
NB. Care should be taken as the size markings will react
in the same way as surface markings and transfer
onto the metal's surface!
The triblet can be hand held or secured in a vice at the
handle (secured at any other point the triblet will be
marked and transfer the marks onto the metal's surface).
