We stock all the recommended grits of
PSA (Pressure Sensitive Adhesive) abrasive lapping film for "Scary Sharpening" (For a brief overview of our selection of abrasive lapping films,
please click here.)
PSA-backed abrasive paper is extremely simple to use. You just peel off the paper backing and press it down on the substrate. It minimizes waste and is easier to handle that other types of adhesive sheets. Most users have found that the
PSA material is flatter, and because the adhesive is applied evenly, more of the abrasive sheet is used so it cuts faster. It is also a lot easier to handle when you want to make your own specially shaped abrasive sticks - for example, for sharpening curved tools.
A good sequence of sharpening is 15 micron (similar to a 1200 grit waterstone), followed by 5 (similar to a 5000 grit waterstone), followed by either the 1 and/or the .3 Micron Aluminum Oxide (similar to an 6000 or 12000 grit waterstone respectively).
We use the 40 micron size (similar to a 400 grit waterstone) for really rough blade shaping and doing the backs of old blades when we first get them.
We offer the grits individually or in sets - the selection of the 15, 5, and .3 grits mentioned above or a kit with all 5 grits.
The 40 and 15 micron sheets are marked. 5 micron film is gray with no markings, 1 micron is lime green, .3 micron is white. 8 1/2" x 11" sheets.
