I tie most of mine direct to the knife,I would have to have the knife to do that.Most people but the loop end through the hole in the scale,then put the body through the loop and tighten down.Good thing about doing it this way is that you can remove it if you want to use it on another knife.
The Body is about 2in and the loop is about 3 in.I can do them in other lengths but IMO this is the size that looks best on a folder.
Thanks
