Mason's trowel
Hand tool for mixing, shoveling and spreading mortar over stones, walls,
floors, ceilings, etc. It is also used to chop off stones and to collect
the falling mortar during grouting. It consists of a rounded or pointed
metal blade attached to a short straight handle with a bent stem. The blade
is usually quite large (approx. 16-19 cm / 10-15 cm), in contrast to the
blade of the plasterer's trowel. [MOT]
