Scary Sharpening Abrasive Sheets

by 3M

The Scary Sharpening abrasive sheets provide a quick cutting, long lasting and very flat sharpening method. These Aluminium Oxide microfinishing sheets are easy to lay with the Pressure Sensitive Adhesive (PSA) backing.  

Each sheet is approximately 280mm x 230mm which can be cut to maximise the use of the sheet for scary sharpening tasks.

We use these abrasive sheets for sharpening in our attached workshops at the Peter Sefton Furniture School. It has been very well received by the students and has become many students sharpening method of choice over the years.

Originally designed for use in the demanding field of metalwork microfinishing for grinding of cam shafts and offers excellent results in hand sharpening. The abrasive cutting is quicker, lasts longer and is less prone to tearing during use compared to the original lapping films used for fibre-optic polishing.

Here's a guide to help you to select the micron size, but you will find how it works best for you with experience. The higher the micron or U number, the coarser the grade.

  • 80u (180 Grit) Black - For removing original grinding marks on new blades or grinding the primary bevel; cleaning or initial lapping of plane soles to remove damage or rust.
  • 40u (360 Grit) Blue - Used for flattening new chisels and plane blades (if required) initial primary bevel forming and lapping plane soles
  • 20u (1000 Grit) Red - Great for general secondary bevel and backing off chisels and plane irons.
  • 15u (1200 Grit) Orange - Refining secondary bevels on chisels and plane irons and backing off.
  • 9u (2500 Grit) Light Blue - Produces micro bevel and backing off chisels, plane irons and knifes; should cut hair but the edge can be improved if required.
  • 3u (8000 Grit) Pink - Produces polished micro bevel and polished chisel backs, plane irons and knifes; this will give the finest cutting edges available.

Great abrasive paper

Can easily cut to width to get muiltiple grits side by side on my honing surface. Working through the grits gets a great edge to my chisels

Excellent results

I am very pleased with my purchase. These sheets seem to last longer than expected. Yes, un-sticking them can be tricky, as they leave quite a lot of the adhesive and print from the sheet. However WD40, Isopropyl alcohol etc soon fixed that.

Worked a treat

Added the final mirror edge to my plane blade. Would happily recommend.

Sharpening aid

Used a progressively finer grade mounted on MDF to sharpen plane blades producing really sharp edges on micro bevels.


Can't recommend these highly enough my plane blades have never been as sharp especially my router plane bit not sure on the longevity of the sheets yet but hey at £4.00 a sheet does it really matter great service from WWW yet again
