The scary sharpening technique has evolved somewhat with the advent of modern film-backed superabrasives, more commonly referred to as lapping film, which significantly outperform and outlast ordinary wet and dry.

Scary sharpening offers a clean, fast, consistent and cost effective way for novice or hobby woodworkers to achieve professional results without the initial outlay for a full set of bench stones.

Workshop Heaven supply various grades of PSA backed lapping film sheets that have been carefully selected for use with the scary sharpening method offering efficiency, ease of use and long service life.

Originally developed for polishing fibre optics, 3M lapping film is fast cutting abrasive system that provides precise, consistently uniform, close-tolerance finishes.

A high-strength polyester film backing is coated with premium, micron-graded mineral particles that are electrostatically oriented for greater cutting efficiency. The particles are bonded into a layer of resin that wears away slowly for increased durability. PSA is the acronym for Pressure Sensitive Adhesive and is a heavy duty version of the adhesive on the back of a Post-It note.

To use, cut each sheet into the desired width, peel the backing and fix a strip of each grade next to each other on a piece of float glass or other perfectly flat substrate applying firm pressure for an even secure bond.

Scary sharpening is a less expensive option than waterstones in the short term, ideal for the occasional woodworker, or a handy way to temporarily fill the gaps as you build up your waterstone collection. Lapping film can be lubricated used with water, oil or paraffin. If using a combination of stones and film though we recommend using water as a lubricant for the lapping film to avoid contaminating your waterstones.

    I have and use the 'scary sharp' system instead of stones, much better results, clean and flat way to sharpen on. Would recommend.

    Sharpening System

    Posted by G Hope on 3rd Dec 2014

    This was first sheet in my system for sharpening knives instead of expensive water stones. I have since added a 5micron to get the edge started then the 3, 1 and then 0.3micron for final polish. The finish is superb and would recommend them instead of the water stone alternative a great saving.

    I bought this to see if I could get a really shiny finish on the backs of chisels, etc. - and its working. But the real reason to write this review is to tell the world about the fantastic service of Workshop Heaven. We exchanged extensive emails of good advice before I ordered.
