The braided steel line from the fishing section of the local tackle store is what I use for my snares as well. I precut several and used the small steel crimping collars (sold in the same section of the store) to form the small eyelets at each end of the snare. (Less construction time in my lap under a tree). And they can be used for other things as well such as "choke" one around a cup to hang over a fire.
