Tomato stakes
, like you said quiver stiffeners, or for use in weaving other material around them for making quivers, fish trap, craw fish trap, bird trap, ice fishing tip ups, kids arrows, cross bow bolts, for a small cross bow, use as a dowel, where you would normally use a wooden dowel. Make a N.A. Back rest,swagger stick, pointer, long chop sticks, for cooking, just trim one end of each on a long angle on one side, so you have a long taper, and then lightly flatten the other side, and use that side on the inside of your chop sticks, so you have a thin flat end for picking up small, as well as larger pieces of food, while cooking., ram rod, for muzzle loaders, if long enough bend in a hoop, for drying small hides, split into thin slats, and make kites, use them for making baskets, use whole pieces for the ribs, and other material for the weaving. You can heat them, and shape them for unique baskets. Make a folding, or non folding wine rack, clothes hamper frame,split them for shiskabob skewers, and a lot of other stuff I can't think of at the moment.
