## Description

This lapping film is 100% made in the USA by 3M. These micro-finishing sheets have been developed for industrial applications and can be used to flatten or polish just about anything. This lapping film contains carefully graded aluminium oxide particles that are electrostatically coated on a backing made of high strength polyester film. This fast cut, water resistant abrasive offers precise, consistent and narrow tolerance finishes and is available in a wide range of precise micron grades to meet any need for sharpening or polishing. They can be fixed to a flat, hard surface (usually 1/4" glass) and used to get a scary sharp edge on wood chisels or planing irons. They can be wrapped around contoured sticks and used to sharpen carving tools. They can put a sharp edge on all types of knives. They can also be used to polish jewelry or gemstones. They are PSA and have pressure sensitive support. They have a 3mm high strength polyester film backing which is less likely to tear than traditional wet or dry sandpaper. Leaves are not marked, so using their color is the only accurate way to identify them. These aluminum oxide (AO) sheets are available in the following grades: 1) 0.3 micron (white) or 60,000 grit 2) 1 micron (light green) or 14000 grit 3) 3 micron (pink) or 8000 grit 4) 9 micron (light blue) or grit 1800 5) 12 microns (yellow). or 120 Grit 0 6) 30 micron (green) or 600 and 7 grit) 40 micron (blue) or 300 grit. Leaves are not marked, so using their color is the only accurate way to identify. In finer grains, it can be difficult to differentiate the abrasive side of the substrate. The abrasive side will always have a matte finish, where the back side of the film will be glossy.

Review: Sharpening for the gods. Scandi heaven - I bought this to sharpen my razor. It worked better than I could have hoped. The perfectly flat glass underneath will never not be perfectly flat, so you can sharpen knowing that the only problem is you. It's not a dip in your stone. I get such great results for my Scandi grinds. Durability is ok with water, but with wd40 the sharpening results are unparalleled, and the papers deteriorate kinda quickly. At 16$ a pack they are an affordable way to get into knife precision sharpening. I use them more than my $1000+ dollars of whetstones. They make sharpening easier.
Review: Used this on my KME Sharpener and I am loving it! - I bought the lapping add on for the KME which comes with 6 glass plates and 6 different diamond lapping films 9,6,3,1, .05, and .01 (6 each) and it produces an insanely sharp edge with a mirror finish on the blade. The replacement film is a bit pricey which is why I tried the 3M. For less than half the price of what I was using, I get more grit sizes and I can get about 8 films out of each sheet. The results are even better!! I will be a repeat buyer for sure.

### ⭐⭐⭐⭐⭐ Excellent Polishing
*by T***. on February 11, 2025*

Nice distribution of grits allowing easy restoration of my small project. I took a 45 yo hunter style single blade pocket knife and used the product to polish the bolsters and carbon steel knife to near new condition. My grandson will love to have this for his birthday so he has “A knife just like Grandpa’s “.
