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

I purchased these to use with my Worksharp knife sharpening system. I cut them to fit the stone and then just put them on. I get a razor sharp edge and a mirror polish. Very happy with this lapping film.

For sharpening my knives, I use a wet stone and a leather strop. I was content with the results but I knew I could get them sharper. Watched a video and thats what got me interested in these. Using these to get that final polish on my knives has made a huge difference.

Sheets work very well. Problem is durability and quantity. Most will never need all 9 films, youre better off buying sheets of 9x11 in grit needed. You can also get Diamond film from KME which lasts way longer. KME gives you five 4x1 slabs which last about 5+ times longer. These are nice due to size but dont help me. When using KME these sheets will get you through 1 maybe 2 knives that need moderate work. The KME ones will get you through 7 or more as they are diamond. ALWAYS remember to hone away from edge if you push towards edge you will cut film and ruin it. If using KME system you will need a glass blank for film(or alum/glass blank) for backing. The film removes better from glass

Not worth the money

This is the second set I bought. I affixed them to a granite floor tile I bought at the local big box home improvement store. When purchasing this item, you are riding from Taylor Toolworks. They are a GREAT company to order from. I usually order directly from them but I used an Amazon gift card for this order.

I bought these sheets after watching a YouTube video of someone cutting them to size and sticking them to the ceramic hone on a Worksharp Precision adjust knife sharpener. I cut them into sight oversized strips and they adhere perfectly to the ceramic. Knives come out shaving sharp with a mirror finish. You can get multiple uses out of the strips if you stick them to a piece of wax paper to prevent the adhesive from drying out. I can sharpen about 4 pocket knives 3-4” blades using the strips before it’s time to change strips. I got about 14 strips out of each sheet of lapping film. If you do bigger knives they obviously will wear out more quickly. Pull the paper with the cutting edge towards the apex, don’t push the paper into the cutting edge or you will slice it. I also buff side to side and it doesn’t cut the paper, and finish with 10 strops along the knife blade from hilt to tip on each side and finish with 50 strips each side on the 60,000 grit white film. This stuff is awesome and I will be purchasing more when I need to.

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

As advertised.

These work great for getting a mirror polish on a knifes edge

They were shipped as promised, will allow me to make 11 sets of each grit, the only problem I noticed was the light green sheet was cut to 3-3/4 not 4-1/4
