Some say to shred it when wet,but i dont like handlein wet gooey slippery sinew n try to strip it.I see and read many accounts,where they try n pull it apart,from end to end.I find it much easier to pound it,then start pullin it apart from the center out.I get less waste,longer strings,and generally do it with my hands,after the initial pounding.You can have that 2 pliers method.LOL
Other than that,i dont really think there is any real EASY way to process sinew,other than buyin or tradein it Processed.If workin sinew,really aint yer thing,there is always selfbows,and other materials fer lashin fletches.
