i think you can still make an unbacked 5 curve IF theres no knot in that handle area...if not then i think it would be safe to heat that area and take a lil bit of that setback out. if there is a knot there you can take some of it out in each fade area as well,but carefully is the key word to either way.you ll have to slowly ease her down lil by lil,step by step,twist by twist of a clamp with dry heat. once pliable ease her down a lil to the point of where it just starts to tighten up,then stop,reapply oil and keep heating it,then repeat till your just a hair past your desired goal. understand amigo?
