My wood turner friend, Richard Shock, has a line of paperweights with inlaid centre.
This is one from his range with a silver disc centre. I provided the discs and also the silver matchstick that is use to displace the disc by pushing from the rear. The disc can then be cleaned without the cleaner damagiing the wood.
You can buy this paperweight from Richard’s website
If you lose the matchstick – come to me!
