Abstract
A manual planing machine, has a planer shaft having at least one longitudinal slot, an elongated flat planer knife clamped in a detachable manner in the and formed as a dual-cutting mini reversible tip with at least one cutter and with a back groove extending parallel to the cutter and with a holding rib on a side of the longitudinal slot to prevent an intentional detachment from the planer shaft, the planer knife carrying only one the cutter, extending in a corrugated manner in such a way that troughs of the cutter lie on a common first straight line having the same spacing relative to the back groove as a cutter of a mini reversible tip, while its crest lie on a common second straight line which extends 0.5-1.5 mm radially above the first straight line, the planar knife carrying a contact edge which is right-tangled and is flattened relative to a back, instead of another cutter at a side located opposite from the at least one cutter for support at the radial stop of the planar shaft.
