HAHA Troy I learned that lesson also, fortunately my dog only got to a few strands but I found out because she was caughing and had 6" of sinew strands sticking out of her mouth (pugs are not adapted for eating stringy treats). After pulling the sinew out (weird) I decided not to process sinew on the floor anymore.
John, I'm with you on that ... I've got to be feeling like really punishing myself. My next one will likely be osage,
or maybe yew if I win the lottery or someone with alot of yew decides they need alot of sinew ... both of which seem unlikely.
