Toss 'em!!! I landed a 21# coho at Astoria this fall (clipped ), and while checking the gear afterwards, I had a chain swivel that looked just like your picture. Except the eye was straightenend out, and the knot was hung up on the burr caused by the kink/crimp at the end. A lucky one no doubt :p . No more cheap stuff for me. It's a 330 mile trip (one way) and I make about 10 trips over a year, so whats a few more $$$$$!!!
