I'm going to be rehandling and 20-something year old wusthof chef knife with a built in bolster. The inside of the bolster has a sweeping curve beneath the handle scales which I know is going to be a pain to fit perfectly. Any tips for matching the radius of that curve better? Seems like when I look around, everyone just squares off the shoulders but, in my opinion, that looks cheap. I do still have most of the old scales so at a bare minimum i can trace the radius over and go from there.
