The present disclosure provides a drywall tool including a scraping portion having an outwardly curved front portion extending between parallel side edge portions and a support member joined to the scraping portion by at least one fillet. The scraping portion may also be flexible to conform to the inner wall and resilient enough to prevent bending of the scraping portion around hardened putty or other materials attached to the inner wall of the bucket. The fillet may also provide a smooth connection to facilitate cleaning of the drywall tool.
