A sharpener, specially for the pencils, is made of a shell and a metal blade. At the upper end of the shell there is a funnel or alternatively two funnels placed side by side. The metal blade is V-notched or U-notched with the opening upward and is placed in the middle of the single funnel or in-between of the two funnels alternatively. The pencil core can be sharpened on the edge (sharped or right-angled) of the notch.
