Made entirely in the USA, these water-resistant, pressure-sensitive adhesive sheets provide precise, consistent finishes for sharpening and polishing tools, knives, jewelry, and more. ## 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. ## Features - Pack of 7 sheets containing the following micron sizes (0.3, 1, 3, 5, 12, 30 and 40) - Pressure sensitive adhesive (PSA) with 3mm high strength polyester film backing - 100% Made in the USA - Measures 4" x 11" - Aluminum Oxide (AO) Abrasive Material ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TDMS1H8 | | Backing Type | Film | | Best Sellers Rank | #281,258 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #992 in Sander Sheets #9,068 in Abrasive & Finishing Products | | Brand | Taytools | | Brand Name | Taytools | | Color | weiß | | Compatible Devices | Air Sander, Angle Grinder, Delta Sander, Drywall Sander, Hand Sander, Mouse Sander, Multi-function sander, Orbital Sander, Sanding Block, Straight Line Sander | | Compatible Material | Metal | | Customer Reviews | 4.6 out of 5 stars 748 Reviews | | Grit Material Type | Aluminum Oxide | | Grit Number | 600 | | Grit Type | Fine | | Item Dimensions | 157.48 x 39.37 x 0.1 inches | | Item Dimensions L x W | 157.48"L x 39.37"W | | Manufacturer | Taytools | | Material Type | Aluminum Oxide | | Model | 279175 | | Part Number | 279175 | | Product Dimensions | 157.48"L x 39.37"W | | Set Name | 7 Sheet Pack | | Size | 4-1/4" x 11" | | Size Name | 4-1/4" x 11" | | UPC | 737787279175 | | Unit Count | 7 Count | ## Product Details - **Backing Type:** Film - **Brand:** Taytools - **Color:** weiß - **Product Dimensions:** 157.48"L x 39.37"W - **Size:** 4-1/4" x 11" ## Images ![3M (R) 7 Sheet 4-1/4 inch x 11 inch PSA Lapping Microfinishing Film for Scary Sharp Sharpening System Aluminum Oxide AO - Image 1](https://m.media-amazon.com/images/I/51VPcuR8isL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sharpening for the gods.

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 “. ## Frequently Bought Together - 3M (R) 7 Sheet 4-1/4 inch x 11 inch PSA Lapping Microfinishing Film for Scary Sharp Sharpening System Aluminum Oxide AO - Taytool 279205 Three Sheets 5/16 x 5 x 12 Deal Flat Float Plate Glass with 7 Sheets 3M (TM) Lapping Microfinishing Film 4-1/4 x 11 for Scary Sharp Sharpening System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/158513887-3m-r-7-sheet-4-1-4-inch-x-11](https://www.desertcart.pt/products/158513887-3m-r-7-sheet-4-1-4-inch-x-11) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-14*
