Ok Folks heres the deal. Was in to my local archery shop to get a new string but on my bow. I go pick it up and bring it home to shoot and run 15 arrows through it and notice that the d loop they installed starting fraying really bad to the point where I was afraid to shoot in fear of it breaking. So took the bow back to have them reinstall an new loop. The guy tells me that he will do it quick while I wait. So I turn around to look at some products and all of a sudden I hear "Thwang" and look over to see me string on my bow cut in half. So now my question is, could there be damage to my limbs by this guy straight up cutting my string with out the bow in a press. To me seems like it would almost be a dry fire. Any input would be great. Thanks in advance!!
