2 Barbed Items
I tested 2 barbed sewing kit, barbed hide items on TC. One was worth 34 points and the other 18 points. Those were the leftovers that you usually toss on the ground.
Making the items used average 10 barbed hides each, 20 points each there, plus one barbed kit charge each, so it looks to me like runic crafted items are worth less than the materials used to make them. I did not test any imbued items.
