I don't have any sinew, but, I have a few knife blanks, an end piece of water buffalo horn, some bamboo backing strips(2 total), 2 board pieces of yellowheart(59 inches long by approximately 2 inches wide and over an inch thick) and two osage board pieces(approximately 36 inches long a piece by a little over 2 inches wide and a bit over 3/4 inches thick). I also have 5 pieces of bloodwood that are 58 inches long each and between 1 3/8 to 1.5 inches wide.
