This time a CH1 Super is the culprit. It's less than a week old and a crack has developed on the top of the handle (where the knot joins). It's very small now but it looks like a stress fracture (perhaps from the knot being overstuffed?) that will likely continue to open. I'm hoping against hope that the crack will stop where it is. I really don't want to send this back. Anybody else experience this? If so how bad did it get? Thanks.
