Our contractor-grade QLT Brick Trowels come in the standard patterns: London, Wide London, and Philadelphia. You have your choice of blade length and width as well as a soft grip, no-slip plastic, or standard hardwood handles. London Brick Trowels have a narrow blade profile. MARSHALLTOWN offers a narrow or wide London Pattern. The London brick trowel pattern has a rounded heel and carries mortar farther forward on the blade, making it ideal for brickwork.
