When I repair a blade I always hit the end with CA before I put any tape on. If the weight is showing I trash the pair. Haven't had a weight fly out yet, but anytime you repair them you take that chance. Use common sense, I know there are guys out there screaming at the top of there lungs "Never repair blades!!!!" but I'm cheap and if there's a chunk missing I trash them. Split monocoat happens with practically any scuffle. I've had brand new blades come with split monocoat.
