From Michael Hall
At last scientific proof of what I and many other DIY furniture assemblers have known for a long time: that the cross-cut screw is vastly inferior to any other type (Technology, 3 December) and has an amazing consistency in that the cut gives way when the screw is approximately two thirds of the way into the wood. Can we now look forward to consumer groups campaigning to abolish this major source of stress in the modern household?
