Abstract:
1. A putty knife, comprising: a substantially planar permanent non-disposable blade made of a base material and having only selected working edge portion(s) of the blade that are made harder than the base material, a handle that is coplanar with and connected to the blade at an edge portion of the blade distinct from the working edge made of the base material that has not been made harder, whereby the permanent non-disposable blade is made more durable so as to have a longer useful life with improved durability, strength and/or resistance against wear and the blade-to-handle connection is made more durable so that the putty knife does not need to be reworked or disposed of as often.
