Spratt discloses a hockey stick blade having an abrasive
material bonded or secured to the blade by an appropriate
adhesive and a method of applying the abrasive material and
adhesive to the blade. The method includes the steps of
applying a quick-drying thermosetting non-absorbent adhesive
to a wooden hockey stick blade and spraying a moisture-
absorbing abrasive grit on the adhesive. Spratt teaches that
“the abrasive grit may be carborundum, sand, aluminum oxide
(alumina [also known as corundum]), silicon carborundum or
even a glass grit” (page 3). For quick repairs during a
hockey game, Spratt prefers a grit which absorbs moisture from
the adhesive, particularly an alumina grit such as Alundum
oxide, because the alumina grit absorbs the moisture in the
epoxy, thus providing a quick-drying technique (page 3). On
page 4, Spratt teaches that, if the abrasive grit is to be
