    These are pretty good lapping films. Puts a mirror polish on most metals.

    These are great. Very easy to use one you know the proper technique. They produce an absolutely stunningly sharp edge on the chisels, planer blades, and knives I sharpened

    This works really well, dry or with lapping fluid. I dont know what else to say other than this stuck well, cut well, and left consistently sharper edges than I have ever gotten with my stones and strop. As long as you dont accidentally slice one, they last a good long time too, especially as you get into the finer grits. I wish it were a more permanent solution (like stones) where you are only buying once, but this has such an array of grits that even as I add more stones to my collection, there will still be some levels of fine that I can less expensively get with these sheets.

    There is no marking on the sheets as to which grit each sheet is.

    Effortless keeping my chisels supersharp.

    These are almost as good as stones. Will buy again.

    The product works as expected, but very pricey. I wish there were other cheaper options. I used this product to remove rust from my knives.

    Nice price on this wide variety of lapping films. Puts a keen edge on razor and knives.

    Very easy to stick to a piece of float glass without bubbles so long as you follow the tips with washing the glass then wetting the glass first. I had some old chisels that were in pretty rough shape that are now razor sharp. Coupled with a honing guide, these sheets made quite work of each chisel.

This lapping film is 100% made in the USA. These microfinishing lapping sheets were developed for industrial applications and can be used to flat lap or polish just about anything. This lapping film contains carefully graded aluminum oxide particles that are electrostatically coated onto a high strength polyester film backing. This fast cutting, water resistant abrasive provides precise, consistent, close tolerance finishes, and are available in a wide range of precise micron grades to meet any sharpening or polishing need. They can be affixed to a hard flat surface (usually 1/4 inch glass) and used to get a scary sharp edge on wood chisels or plane irons. They can be wrapped around contoured sticks and used to sharpen carving tools. They can put a wicked sharp edge on all kinds of knives. They can also be used to put a fine polish on jewelry or gem stones. These are PSA and have pressure sensitive backing. They have a 3 mil high-strength polyester film backing which is less likely to tear than traditional wet or dry sandpaper. The sheets are not marked so using their color is the only accurate way to identify them. These Aluminum Oxide (AO) sheets come in the following grades: 1) 0.3 micron (white) or 60.000 grit 2) 1 micron (light green) or 14,000 grit 3) 3 micron (pink) or 8,000 grit 4) 9 micron (light blue) or 1800 grit 5) 12 micron (yellow) or 1200 grit 6) 30 micron (green) or 600 grit and 7) 40 micron (blue) or 300 grit. The sheets are not marked so using their color is the only accurate way to identify. In the finer grits, it can be difficult to differentiate the abrasive side from the backing. The abrasive side will always have a matte finish, where the film backing side will be glossy.
