How faithfully will a scraper follow a surface? In the picture you can see a dip in the limb. It's about 4" long, belly at the bottom. If I just take even scrapes along the length of the limb will it follow the shape or will it eventually flatten the dip and possibly make a hinge in that spot. I've been avoiding long scrapes and kind of doing the limb in three sections to maintain the shape but I wondered if the scraper would do that on it's own?
