Here is a simple, reversible and cheap way of making this sort of pin-vice easier and more comfortable to use.... Force the 'handle' end into a firm pencil eraser until it goes right through, much like a hole punch. Then, using a dressmaking pin secure one half of a suitably sized pop-fastener into the rubber trapped in the end. Now you can push and twiddle more comfortably and accurately because the handle end rotates nicely against the palm of your hand. Simples! [insert annoying Meerkat noise...] Doug
Great idea Doug, that'll save me having a sore palm and/or a blister! The simplest ideas are always the best. Keith.
