Looking at the inscription, it could be ..rena en Toledo, or something close to it. 
 
One name I found that could possibly be it, is Baena, since it is easy to confuse R and A in that script.  There was a sword smith Baena Antonio de Toledo, don't have any other information on him.   
 
The other side is hard to read.
