An electric knife includes a cutter blade, a handle, and a drive unit and a driven unit mounted inside the handle. The drive unit includes a first movable sleeve. The driven unit includes a second movable sleeve. The cutter blade is set on the second movable sleeve. The drive unit and the driven unit are connected through a link, so that the drive unit can drive the second movable sleeve of the driven unit and the cutter blade to reciprocate along an axis.

A winder unit is disclosed for use with a cutting wire in cutting out a vehicle glazing panel. The unit is capable of being mounded to the glazing panel and includes first and second winder spools for winding cutting wire. At least one wire wrap around guide element (typically a pulley) is positioned away from the mounting means. The unit may be used in various techniques either alone or with an auxiliary guide arrangement.

An oscillating blade including a shank having a tool mounting end and a blade end, the shank defining a longitudinal shank axis extending from an oscillation axis of the tool mounting end, the longitudinal shank axis defining a longitudinal direction. The oscillating blade also includes a first shank extension extending from the blade end in a first lateral direction and having a first cutting edge directed in a first cutting direction, and a second shank extension extending from the blade end in a second lateral direction and having a second cutting edge directed in a second cutting direction. The oscillating blade also includes a shaving edge disposed on the blade end. The first shank extension is spaced from the second shank extension in the longitudinal direction, and the shaving edge is at least partially disposed between the first shank extension and the second shank extension in the longitudinal direction.

An electric utility knife having a blade which can facilitate manual precision cutting, at a singular consistent speed or varying speeds, without requiring the user to exert extreme or substantial manual pressure to cut through a material. The blade can be configured as a vibrating/oscillating/rotating blade to perform a majority of the cutting tasks. The user may simply guide the blade and exert minimal manual pressure on the knife. This can reduce the potential for injury and other repetitive motion stress injuries to a user. This can also facilitate greater cutting precision and can reduce cutting time.
