This piece is really a test piece as it’s the first I’ve made. I’ve been thinking about making a padlock for some time, but, at this scale, making even a basic key mechanism is outside my skills. Then I saw a knitting stitch marker and that method of closure seemed to be the answer. This one is about 4cm tall, 2cm wide and 5mm thick. It weighs 12g.
To open the loop is pulled up, then squeezed in slightly so that it can be rotated through the slot. Simple and secure. Available from my shop and other sizes available to order.
