3M (TM) 7 Sheet 4-1/4 inch x 11 inch PSA Lapping Microfinishing Film For Scary Sharp Sharpening System Aluminum Oxide AO

Works like a champ getting that extra edge of sharpness

I was skeptical at first, but this stuff is a lot easier to use than regular wet sandpaper. It comes with a huge assortment of grits, really more than is needed. Id rather just have 2 sheets each and half the assortment. Its tough to tell the grits apart, so keep track of the colors and mark each one. It comes with some printed info too (see pic). Originally mine showed up with this bit of odd staining but they quickly sorted it out.

Like many woodworkers, Ive spent a lot of time and effort in finding the most convenient, but effective, method to sharpen our chisels and plane irons. I could start a second hand store with all the products Ive tried but dont use due to one issue or another. Lately Ive used wet/dry sandpaper on marble slab with excellent success. My tools come out extremely sharp and the process to touch them up is reasonable. The only real issue is the expense of changing the paper so often. In steps the Taylor Tools answer to the scary sharp method using 3M lapping film. The advantage to sandpaper is two fold. First, the film provides longevity that paper backed products can only dream of ... secondly, the finer films take my tools to a whole new level of sharp. What a pleasure it is to use my tools again. I havent counted just how many chisels and irons Ive sharpened with any given set, but I can tell you that for me its been significant. I have five stages mounted to a 12x24 marble plate to create and maintain my micro bevels. It takes a mere couple of minutes to touch tools back up once you have a good primary bevel established. This is my current soup du jour of sharpening and Im going to be quite satisfied with it for a long time to come.

Im used to using files and wet stones. Decided to try this for my wood chisels. They are scary sharp. Easily shaves hair off my arm an slices through wood with little effort, which gives greater control. Wish I would have switch to this when i first heard of it.

Love 3m products. I use small chisels on a daily basis and these true up an edge really well really quickly! Must have in addition to your glass or stone.

I love 3M the best for sharpening!

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.

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

Not worth the money

Works as promised,however this set needs either a 5 or a 6um to make it a decent product.I trim them into 4×1 strips for my KME sharpening system.
