Workshop Heaven Ltd's video: Workshop Heaven Sharpening Chisels - Practice

Matthew Platt from Workshop Heaven (http://www.workshopheaven.com) demonstrates the benefits of concave chisel backs by sharpening and honing a Narex 8116 Cabinetmakers chisel (http://www.workshopheaven.com/tools/Narex_8116_Cabinetmakers_Chisels_Black.html) using the scary sharpening method (http://www.workshopheaven.com/tools/Scary_Sharpening.html). Scary sharpening, a method of sharpening which uses sheet abrasives on glass is not a new idea, but it is a very effective, affordable and versatile method for sharpening chisels and plane blades - especially when using 3M lapping film. The Workshop Heaven Scary Sharpening Kit (http://www.workshopheaven.com/tools/Scary_Sharpening.html) covers honing and grinding with the inclusion of the more aggressive 100 micron film for grinding, 40,30 and 5 micron for day to day sharpening and some of the finest grades for situations where you need the ultimate cutting edge.
