Editorial Review This handy little spring bar tool from Hobby Tool Supply is everything you need for the occasional watch band resize. It features a spring bar fork and a pin pusher. "Watchmakers Tip" when faced with a design that requires both ends of the spring bar tips to be removed at the same time. Simply remove one end first and block the tip from going back into the hole with a piece of paper, then proceed to remove the tip on the outside so you can now remove the bracelet.
