sharps
Half-step up symbols
Sharps are objects with edges or points that can cut or puncture—especially medical waste like needles, syringes, and scalpel blades requiring special disposal: Put used needles in the sharps container.
In music, sharps are notes raised a half step, or the symbols indicating them.
In gambling, sharps are skilled bettors who consistently beat the odds.
