Compact Grain/Cluster metal working belts can last three to four times
longer than AO belts. They leave a satin,
brushed look on metal. Knife makers and sharpeners love them. Due to
the chunks of grain, their
appearance is much rougher than their stated grit. It is advisable to
break in each belt for 30 seconds with a piece of metal. Thereafter the
grit remains consistent. When the grit on these durable belts is
consumed, many of our customers add polishing compounds such as
jeweler's rouge for extended use. Polishing belts are made from natural
cork without grit.
