    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.

    Not good for honing straight razors. Pitched in the garbage.

    Used to sharpen a straight razor with incredible results. I only used the 8k grit paper and stripped the razor. That was enough to take the razor from tugging terribly out of the box from Dovo to a buttery smooth shave

    I bought these to see how well they could do for getting a mirror edge on my Spyderco knives with my KME. So far not bad, I cut strips to fit on my glass slides like my diamond tape and so far so good. While not as good as my diamond tape, for the price its very good. I would buy them again.

    Great product, I mounted 6 of the sheets (cut in half) on a 1cm thick sheet of float glass. They all worked great on the 25 degree bevel for push-pull, but for the 30 degree bevel its much safer to use the pull method, to avoid tearing the sheet.

    Used this with the worksharp sharpener. Used it then threw a slit of that light green paper on it and in no time was able to slide hairs right off my arm, would definately recommend. Since the light green is one of the smaller grits this means i can go sharper, but this is great for what i need.

    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.

    The lapping paper I received was not a PSA backed paper it was just a fabric backed lapping paper. Not impressed with getting something different than what was listed.
