ABSTRACT:
A sharpening device for sharpening operative instrumentation having a gripping handle4and an acutely angled receptacle support6, both of which form a radiated palmer contour8, and both of which have flattened self balancing table rest10terminations. The hone receptacle6has an attached offset rectilinear container or whet-stone receptacle12with guard walls16that extend above a contained whet-stone14. The instrument entry channel18is a shorter wall that allows full usage of the whet-stone surface without forcibly influencing sharpening angulations due to an excessively high wall. The offset receptacle support6and whet-stone receptacle12create two overhangs or a vertical locking rest20and a horizontal locking22rest that engage with a table. The locking rests coupled with the angled handle4receptacle support6and resultant palmer contour8permit two ergonomic holding positions that allow for both vertical and horizontal honing orientations.
