KME Diamond Lapping Film Set with glass base, 6 micron

The KME Diamond Lapping Film Set with glass base, 6 micron is the start of the last part of the sharpening process. The lapping films have a polishing effect. The set is comprised of five individual lapping films, plus a glass sheet that serves as a base for the lapping films. You place the whole in the [sharpening stone holder](/en/pt/-kme-sharpening-stone-holder.htm) of the [KME Precision Knife Sharpening System, Diamond Stone Kit](/en/pt/-kme-precision-knife-sharpening-system-diamond-stone-kit-kf-d4.htm) or the [KME Precision Knife Sharpening System, R.P.S.H. Combo Kit](/en/pt/-kme-precision-knife-sharpening-system-r-p-s-h-combo-kit-kf-cbo.htm). KME indicates that the 6 micron lapping film corresponds to 3000 grit.
A lapping film is basically very find sandpaper. In this case very fine diamond crystals were placed on a flexible paper base. These diamond crystals are almost invisible to the naked eye. The lapping films slowly remove material and are therefore not suited to sharpen a blunt knife. They are, however, great when sharpening an already sharp knife.
We recommend starting with the 9 or 6 micron lapping films and only use those after the KME Gold Series diamond-coated sharpening stone extra fine 1500 grit or the KME ~1000 grit Hard Arkansas natural sharpening stone. This are the finest KME sharpening stones. You could, however, always use a finer sharpening stone. Afterwards, you can proceed in steps to the finest 0.1 micron lapping film. As soon as you start using these fine lapping films you will end up with a razor-sharp, mirrored edge.
Tips: Always sharpen away from the edge! As such the knife won’t cut into the lapping film.
KME recommends using a little bit of oil as you polish your knife. Even vegetable oil will do!
Don’t use any force. You can use a lapping film approximately 5 to 8 times. As soon as you apply too much pressure the lapping film will not last as long!
