A scalpel, in particular for ophthalmologic applications, having a handle head and a blade, wherein the blade, which includes a blade shank and a blade face, is inserted into a handle head of the handle, and at least one cutting edge is formed on the blade face, wherein the blade shank is configured together with the blade face as a body on which a continuous smooth rear surface is formed, whereby the front of the body opposite from the rear surface forms a cylindrical surface in the area of the blade shank and forms the top of the blade in the area of the blade face, and the end of the handle head has two surfaces that are slanted with respect to each other and that abut, like a roof edge, in an edge that is perpendicular to the axis of the handle, and whereby, in a first of the slanted surfaces, there is an opening for inserting the blade, whereby the inserted blade comes to lie in the opening in such a way that the smooth rear surface is flush with the first slanted surface.本発明は小刀、特に眼科用途のための小刀に関する。柄の頭部（４１）において、互いに傾斜する２つの表面（４５・４６）がくさび状または屋根状に形成される。第一の傾斜面（４５）において刃の突起部（１２、２２）が挿入される開口部（４４）が設けられ、挿入された刃（１２）は後面（１４）が第一の傾斜面（４５）と同じ高さとなるように開口部（４４）内に配置される。柄の頭部の第一の傾斜面は柄の前後軸に対し、２５°から３５°の間、好ましくは３０°の角度で傾斜する。さらに、刃（１０）が柄の頭部（４１）の端部を越えて延伸する仮想の包絡面（５０）の範囲内となるように、刃（１０）の長さを定める。
