On skins and other punched parts where there are curves or bends in the punched area there are significant burrs on each side of the curve that I am finding difficult to debur without taking off quite a bit of material from areas around the curve. If I use a flat needle file it leaves a notch that could create a stress concentration, so I have been using a curved needle file but it is necessary to increase the radius to maintain a well curved surface. This creates a slight hump. I wanted to get some feedback and possibly some photos or examples of how other handle these areas.
