This Spring Bar tool is an ideal and cost effective means of changing your leather watchstraps. All metal body with mm and inch scales for convenient measurement. Flat sided hexagonal main body - so it stays where you put it down and will not roll around your work surface. Supplied with two threaded metal tips, one forked for compressing spring bars in 'blind hole' type case lugs and the other for open hole designs, ie. those with external access to the spring bar. Overall length (including replaceable tips) = 150mm
