4 inches

These otherwise excellent dividers are spoilt by the very poor grinding of the points. As received the the points were ground to different lengths, by grinding 3 flat faces on them. After correcting this, and finally finishing on an oilstone the dividers are very good. They are well made, with very play in them. For the price these are good value for money, if you are prepared to spend some time reshaping the points.

For a beginners leatherworking tool, this is really good quality. The points are sharp and the dial allows an amazing amounts of control.

Nice sturdy construction. I had to file one of the legs to match the length of the other. We’re talking fractions of a mm. Now I think proportional dividing is my new favorite thing! LOL. Well it is when it accurately measures and marks the string spacing on an acoustic guitar. . It does that well.

Nice heavy spring and very sharpened ends, this is a quality set

There’s no movement when set. It’s very stable. Both tips end at the same point so taking even one milimeter is possible. The spring is very strong though. It might be desirable for the type of craft you do. I’m thinking of filling the spring down a bit to make it a bit weaker, it really requires a bit of strength to compress otherwise.

A la fois robuste et précis, ce compas me paraît en outre très solide.

This seems to be of good quality. The mechanism works well and it has good sharp points. Seems durable. Happy with purchase.
