The authentic Japanese Screw Punch was first invented in 1977 and brought to our attention by Christopher Clarkson. In recent years there has been a raft of cheap imitations which, on close inspection, vary greatly from the original design produced by My Kiichi Nonaka. This was witnessed at the 2012 Moulin du Verger 'Handmade Paper and Limp Paper Binding' summer school when an imitation punch purchased for the course would not work. There were significant differences but, on first sight, it was hard to tell the copy from the original. However, the punches we sell are marked on the ferrule with the text 'SCREW PUNCH MADE IN JAPAN'. Some are also modified by us to a design of Christopher Clarkson which allows the mechanism to be locked when making holes at an angle through several layers, an example being limp vellum bindings as featured in Christophers book on the subject. This is not a feature found on the cheap imitation tools.
This tool was designed for making holes with controlled 'torque force' in a variety of materials. Downward pressure causes the bit to spin and drill down through a variety of materials quietly and smoothly and without blocking or snagging.
A great little hole-cutter that is quiet, fast and efficient at cutting through multiple layers of paper, card, leather and fabric. The Screw Punch tool is supplied as a set with a 3mm cutting bit fitted as standard, which can be changed for any one of 10 further sizes, all fitting the same tool.
Additional cutting bits can be purchased individually in the following sizes:
1.0mm, 1.2mm, 1.5mm, 1.8mm, 2.0mm, 2.5mm, 3.5mm, 4mm, 4.5mm, 5mm
