PROBLEM TO BE SOLVED: To provide an exclusive plane for channeling a thread channel which can form a narrow channel hole for fitting a net on the outer periphery of a frame of a landing net used for fishing. SOLUTION: In a plane 1 for channeling a thread channel, on the end site of a plane surface part 2 which is a square sheet material with definite length and width and has the same thickness as the width of a landing net, a cutter edge 3 with an edge of a saw or the similar one is inclined at approximately 10 deg.. In addition, on both side parts of a base plate 5 wherein the cutter edge 3 is fixed at the center of the plane surface part 2 by using a stop shaft, etc., so as to project the edge by approximately 1.5 mm from the plane surface part 2, two guide plates 6 and 6 with definite length, width and thickness are fixed on the central parts of the side faces of the base plate 5 in such a way that they are projected by a definite length downward from the plane surface part 2 of the base plate to form a holding channel 7 with a width wherein the frame is fitted.
