    I like to have my chisels and hand planer blades very sharp and these easily do the job and much less expensive then stones. I cut glass to mount them on ( pressure sensitive) works great.

    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

    These sheets fit great on some flat steel. I used them for putting a mirror edge on a few of my knives. If the knife had a burr on it sometimes would produce a small RIP in the paper.

    I like the polish on the end results of my chisels and plane irons. I am not happy with the jump from 1,800 to 8,000, but I have a 5,000 gray PSA sheet still laying around to fill in the gap. I applied the PSA to flat 12 x 12 x 1.5 peace of granite for all my chisels and plane irons lapping. I touch up all the edges on a 10,000 grit water stone. I like the PSA on granite because is stays flat, not like my water stone that dishes really quick. Yes I flatten my water stone often with a lapping plate. But lapping is boring and the PSA on granite just makes it full proof for a flat surface.

    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.

    Effortless keeping my chisels supersharp.

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

    Not quite as durable as I would like for sharpening chisels and plane irons. However they will put a seriously sharp edge.

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.
