I agree with Del, and would further that i don't think making limbs much wider than handles is all that useful. My go-to design for any length has limbs equally as wide as the handle, and the handle will vary in width depending on the density of the wood I'm using. If I'm using a dense wood like hickory or osage, the handle will probably be 2.6-3 cm wide. If somewhat less dense, I might go to 3.2-3.6 cm wide. I also don't understand the allure of a non-bending handle. You got a nice long stick there, why not use the whole thing?
