    I bought these sheets after watching a YouTube video of someone cutting them to size and sticking them to the ceramic hone on a Worksharp Precision adjust knife sharpener. I cut them into sight oversized strips and they adhere perfectly to the ceramic. Knives come out shaving sharp with a mirror finish. You can get multiple uses out of the strips if you stick them to a piece of wax paper to prevent the adhesive from drying out. I can sharpen about 4 pocket knives 3-4” blades using the strips before it’s time to change strips. I got about 14 strips out of each sheet of lapping film. If you do bigger knives they obviously will wear out more quickly. Pull the paper with the cutting edge towards the apex, don’t push the paper into the cutting edge or you will slice it. I also buff side to side and it doesn’t cut the paper, and finish with 10 strops along the knife blade from hilt to tip on each side and finish with 50 strips each side on the 60,000 grit white film. This stuff is awesome and I will be purchasing more when I need to.

    I purchased these to use with my Worksharp knife sharpening system. I cut them to fit the stone and then just put them on. I get a razor sharp edge and a mirror polish. Very happy with this lapping film.

    These films work well when used with flat substrate, though the finer films are easily cut unless care is taken to use only pull stroke. Coarser films OK for back &forth grinding.

    As advertised.

    These work much better than sprays adhesive on sandpaper then applying to glass for sharpening chisels and planes. Easy to apply and just the right size.
