A combined tool for edge-folding and trimming a rim of a panel includes a cutting blade rigidly secured to a tool holder frame, an edge-folding tool slidably received in the tool holder frame, and a biasing spring arranged in the tool holder frame to bias the edge-folding tool outwardly away from the holder frame. The tool is moved in a linear stamping direction, whereby the edge-folding tool folds back and then holds and compresses a margin of a panel workpiece. The tool holder frame and cutting blade are pushed farther in the linear stamping direction, while the edge-folding tool is pushed back into the tool holder frame and compresses the biasing spring, whereby the cutting blade cuts through and compresses the panel workpiece. This forms a back-folded, compressed, and trimmed rim of the finished panel in a single work step using an integrated edge-folding and cutting tool.
