Abstract: A hand-held sander for sanding a curved surface includes a structurally rigid frame having a left hand hold and left channel oppositely disposed from a right hand hold and right channel. An open-ended concave recess is formed between and perpendicular to the channels. A flexibly resilient and flat substrate has a left substrate end oppositely disposed from a right substrate end. The left substrate end is abutting and slidably captured within the left channel and the right substrate end is abutting and slidably captured within the right channel. A center adjustment knob is rotatably fixed to the frame having a female threaded end. A shaft is fixed to a center of the substrate and includes a male threaded end. The male threaded end of the shaft is configured to threadably engage the female threaded end of the knob, wherein rotation of the knob causes curvature of the substrate.
