Abstract

A drywall knife having a handle and a blade securely mounted thereon. The handle includes an elongated inner core having a longitudinal axis, a transverse axis, a front end, a rear end and first and second opposite surfaces extending from the rear end to the front end of the inner core along the longitudinal axis of the handle, the blade being securely mounted to the front end of the inner core. The improvement resides in that the inner core of the handle includes at least one recess having an opening facing the first surface so as to reduce the overall weight of the drywall knife, arid the inner core further includes a lid hingedly mounted to the first surface of the inner core, said lid being positioned and sized to be folded about an axis parallel to the longitudinal axis of the inner core so as to cover each recess. The drywall knife is inherently lightweight due to its design. The drywall knife is mounted onto the blade without the use of fasteners, due to the design of the handle and blade. The drywall knife has an ergonomic handle enabling comfortable and multiple hand gripping. The handle is manufactured by a moulding process which is capable of producing a sign on the handle of the drywall knife while the handle is moulded, the sign lasting all throughout the working life of the drywall knife handle.
