The Hubbard Brick Jointer's distinctive design allows for one tool to create four different joint sizes. The jointer comes with a 1/2-inch, 5/8-inch, 3/4-inch, or 7/8-inch blade sizes that connect to the cast aluminum handle. Wear is distributed during use by simply revolving the tubular steel blade. As the blades wear out with use they can be replaced while keeping the handle. The polished handle shape allows for more knuckle clearance during use. Polished steel makes smooth concave groove every time. This unique tool was designed by a bricklayer with 60 years experience. Proudly made in the USA. Warning: Always wear eye protection when using this tool.
