This knife, designed by Tim Ely, is specifically designed for cutting the edges of a text block. Many bookbinders do not have a massive guillotine or a reliable plough. Artist Tim Ely has been using a round French or Swiss style knife for some time to precisely cut edges. Paper is quite abrasive, so the edge retention of commonly available knives, was poor, and the handle interfered with this different use of the knife. For the past year or so, we have been exchanging ideas and at this point I am pleased to announce The Ely Edge Knife is available for sale. More information here. The blade is A2 steel, Rc 63, 13 degree single bevel. Overall, approximately 9” long x 1.5” wide x .75” for the wood.
