Thanks for sharing your thoughts on the protection of the sapin. My cocker friend use to tell me if you use the leather boot there is little chance of making mistakes while heeling. He's the first guy I saw using the sapin and leather boot combination. He'll wrap the sapin first twice above the spur and twice below the spur, put the boot on and finish the rest of the sapin wrap around the boot to secure it. Back then it was a complete leather boot with paunan. Now with the new leather boot it even makes it lighter. He also does the post mortem inspection of the carcass which wonders me until he told me he was experimenting on finding out if he leans (kiling) the knife edge or I mean twist it where it does not align ordinarily. His theory was that if the point of the blade goes in the cock's body it will come out in a different angle thus will have a crooked cut making it more effective.
