  • Patent number: 7017739
    Abstract: Plastering/cement trowels have sharp edges which can cut a worker when he places the trowel down in a resting position.

An optional sharpening file is attached to the top of the sheath. Various sheath embodiments include a narrowed rear section of a longitudinal slot on the upper member which functions to hold the spine of the trowel in the slot, a rubber membrane stretchable over the blade, a pair of pincer members on the top of the sheath to lock the shank of the trowel into the sheath, a tether on top of the sheath to lock the shank of the trowel into the sheath, and a rear door for the blade slot.
