Abstract
An apparatus for separating adhesively connected material, such as pressure-sensitive labels. A thin blade having a wedge-shaped periphery is connected to a handle which extends angularly upward from the blade. The blade portion is retained in a sheath having inner surfaces of absorbent material. A lubricating substance, such as a silicone fluid, is evenly distributed throughout the absorbent material of the sheath. When the blade portion is inserted into and withdrawn from the sheath, the lubricant is applied to all surfaces of the blade, permitting nearly frictionless contact between the blade and the material to be separated.
