Mickey...all the buff sinew I have gotten has been slashed off by meatcutters...not sinew savers. The pieces I have are about6-7" long...I would suspect if one was trying to maximize the length it should go out to 10-12". You might ask Doug Campbell how his turned out, he saved the legs from the bison they killed when I was out there, and all of them since. I hadda go home before he got that far. (sniff)
I have only ever bashed emu, elk and buff sinews...the buffalo is the easiest in my opinion. feels right too.
