A drywall knife with a retractable brace is disclosed. The knife comprises a handle; a substantially planar, flexible blade hingedly attached to the handle; and a brace having a cross-member wherein the brace is attached to the handle and wherein the cross-member defines at least one substantially non-linear profile wherein the cross-member substantially imparts a substantially non-linear profile to the blade. The knife may further comprise the cross-member defining two or more substantially non-linear or arcuate profiles, and the cross-member may be positionable to substantially impart different non-linear profiles selectively to the blade. The cross-member may further define knobby contact surfaces contactable with the blade. The brace may be substantially T-shaped, and the brace may be retractable.
