Abstract: Blade-sharpening apparatus includes a blade holder that is axially and pivotably movable on an upright post, to enable controlled manual movement of a clamped blade in contact with a sharpening stone supported on an underlying base. The means by which the clamping head is mounted permits adjustment of declination, for producing the desired blade-edge angle, and it permits pivoting of the head for maintaining optimal contact between the blade and the surface of the stone.
