Adjustable Nut Marking Tool

A well designed and made little tool! So much more exciting than a sanded down pencil, but 245 times the price!
Uses 2mm mechanical pencil leads.

About $50 on E-bay. Now available from US sellers, since the direct from China guys have been cut off by the US Postal Service.

If you’re a luthier who needs a tool that screams “I had an uncontrollable urge to spend money” , then this tool may be the perfect new addition to your arsenal of little precision gizmos that get used once, and then sit in the bottom of a drawer; because you put it in a place where you could always find it, only to forget where you put it.
