Unfortunatly I don't know the name or brand but if you see a capper with that feature I'd reccomend it over one that has uncovered metal jaws.
Really? What about all the other thousands of capper that haven't broken bottles?
Just pulling your chain. The problem is not the bottles, but the metal plates (clamps) on the capper.
OP: Check the metal clamps on the capper, specifically the cresent cuts. Look at the back side of the cresents to see if the plate has another set of cresents cut into them. Some of them only have 1 set of cresents cut into them, some have 2. The second cresent cuts are for different size bottle necks...I have a picture of the clamps in several posts in the past, one just the other day.
THart: Your clamps (probably) broke the bottles because the clamps were set for a thinner size neck and your bottles were the (slightly) larger ones.
