What are the dimensions of the joint between the tools and body on a Leatherman Surge?
I was one of a few machinists that made the main pivot pin that links the Leatherman tools in the holder. Because the (stainless steel pin) material was very difficult to work down to the +-.0005 dimensions indicated using standard machine tooling, Leatherman made ongoing changes to the dimensions and material for cost effectiveness. The previous post, buy or use an appropriate caliper to measure would be the best if you are custom making your own tools to mount.
