Every saber ships with a free allen wrench, but not one like this. This is a Bondhus, made in the USA to exacting specs and is quite frankly the best wrench available.
If you are having an issue with your set screws not turning with the wrench you have now, or you simply want the best allen wrench available, this is the one you're looking for. We've been told that this wrench is not locally available everywhere, so we decided to offer them here.
In the saber hobby, this is likely the best 95 cents you will ever spend.
