Metal Chinrest Key

Pros: Good design

Cons: none

Other: I had just ordered a couple of chin rests from stringzone it made sense to buy a chin rest key to fit them

Pros: Very easy to use

Cons: Nothing

Pros: Handy tool to keep in your violin case and at the right price

Cons: I purchased this key at the same time as the Guarneri Chin Rest, Hill Pattern. The unfortunate this is that this key is too big to fit in the rod adjustment holes, so in short a waste of money. Fortunately the Chin rest was supplied with a small key which is sufficient to tighten up the rods (or whatever you call them).
