Hart’s Quick-Tatch trowel system consists of a detachable handle that slides on and off a variety of trowels and floats, making them very easy to transport and stow. The handle can be locked at any point along the spine of the trowel and it also can be reversed, making it easy to work an inside corner with either the notched or flat side. The storage box has a perforated bottom and grooves to keep the trowels separated, so they can be put away wet. One trowel locks into the top of the box creating a lid and the handle can be used to carry the whole thing around. Price: $40/7 piece kit. Also available in a 3-piece kit or individually / COO: China /harttools.com
