This is a most useful tool if you are marcking out lots of holes in wood or metal. I recently made a patch in the bonnet of my vintage tractor and used small M3 set srews closely set to give the impression of riveting. The point to point was excellent at setting out the fine spacing without the need to get the pen and paper out to work out the divisions and the measuring. I have loaned it to a colleague so he can have a go on some of his projects. It has many uses where one might want to set out say fold lines. The tool is well enough made perhaps a little flimsy but certainly value for money.
