We have been grinding Staedtler Mars and Magic Rub erasers with the
Italian 'FIMAR Cheese Grater' since 1993. This machine was
recommended by Elizabeth Morse from Harvard at the AIC Book and
Paper Group Annual Meeting. In order to obtain the best results, we
have modified the machine in a number of ways. The resulting crumbs
are sifted to four different size crumbs, but some pieces have to be
reground because they are too large. We package the crumbs in 1/2
lb. bags. For more information, please contact Bill Minter at:
