The #21 excess removal knife, manufactured by Hu-Friedy, is a specialized manual instrument intended for restorative dentistry. This model is distinguished by its #6 handle with a gold-plated finish, offering a grip adapted to high-precision movements.

Its use is particularly relevant for refining anatomical contours and freeing interdental spaces from bonding residues. As a dental finishing instrument, it helps guarantee periodontal integrity by avoiding plaque retention areas caused by excess material in subgingival or interproximal zones.
