< Topic >At brief, is desired the needle sharpening jig which makes that it sharpens sharply possible is offered to without by the person who sharpens the Tip of the fishhook which is blunted with use.SolutionsCurved surface 1a is provided in the pedestal 1 which was formed with the elastic material, the aforementioned curved surface is covered with grinding sheet 2. The aforementioned grinding sheet makes the length which at the width which is briefer than length of the aforementioned curved surface is settled in the longitudinal direction of the aforementioned curved surface and within size of the direction which crosses, multiple opens interval to the longitudinal direction of the aforementioned curved surface and is possible to be something which is laid out. And, each of the aforementioned multiple grinding sheets is locked by the aforementioned curved surface one of the edge 2of a the longitudinal direction of the aforementioned grinding sheet the longitudinal direction of the aforementioned curved surface according to the direction which crosses, is possible to be something which has become a standing up state where the edge where it opposes with the edge which is locked to the aforementioned curved surface of the aforementioned grinding sheet has left from the aforementioned curved surface. When sharpening the fishhook, it is possible to finish the Tip which paralleling to the curved surface 1of a pedestal, 1 it rubs on multiple grinding sheet 2 and blunts the Tip of the fishhook 3 which is used the Sliding ri by moving, sharply.< Choice figure >Drawing 2【課題】使用により鈍化した釣り針の先端を、砥ぐ者によることなく、短時間で、所望される程度まで鋭利に砥ぐことを可能とする針砥ぎ治具を提供する。【解決手段】弾性材で形成した台座1に曲面1aを設け、前記曲面を研磨シート2で覆う。前記研磨シートは、前記曲面の長さよりも短い幅で前記曲面の長手方向と直交する方向の寸法内に納まる長さとされ、複数が前記曲面の長手方向に間隔を開けて配置されるものであってもよい。そして、前記複数の研磨シートの各々は、前記研磨シートの長手方向の縁辺2aの一つが前記曲面の長手方向と直交する方向に沿って前記曲面に固定され、前記研磨シートの前記曲面に固定された縁辺と対向する縁辺が前記曲面から離れた起立状態となったものであってもよい。釣り針を砥ぐ時は、使用した釣り針3の先端を台座1の曲面1aに沿って複数の研磨シート2上を擦り摺り動かすことによって、鈍化した先端部を鋭利に仕上げることができる。【選択図】図2
