I had a little osage limb that I cut in 1996 and it had been in the rafters of the garage until 2020 when I decided to work it. The growth rings were like 30+ per inch and it was really knobby, so I planed the back flat and backed it with bamboo using the perry reflex technique. The limb was narrow and only about 58" long, but it made a very nice little bow that is still my favorite of all the 100+ I have made. The bamboo is dyed with leather dye, it has a matte finish, and the grip is deerskin. Finished at 54#. Holds about 2" of reflex after being shot in.
