Scary Sharpening Abrasive Sheets3MSCARY-3
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.
