How do mortar rakes work?

	Mortar rakes will have either a grooved or grooved design.
	Both are designed to remove mortar between bricks.
	The grout rake attached to the power tool rotates at high speed and crushes (grooved design) or cuts (grooved design) the mortar.
	Bold design The granules on the sides of the grout rake work the grout, scraping it off the brickwork, leaving a clean surface for re-sharpening.
	grooved design In a grooved mortar rake, the rotating action means that dust and debris are directed along the grooves and away from the masonry.
	Blades on the sides of the tool, forming grooves, cut through the mortar as the tool rotates. The grooves are designed for the passage of mortar fragments.
