A putty knife handle is made up of an upper lid and a corresponding lower base. Both of them form a housing with location holes for insertion pieces and columnar tubes for insertion posts coupled and fixed with each other. The invention is characterized in that the upper lid and lower base respectively form at the front relatively a stepped projecting piece and a projecting seat. At the front of the projecting seats is a slot. Relative to the body of the lower base and behind the slot are U-shaped frames, which enable the clamping end of the blade to be implanted into the two U-shaped frames after being inserted through the slots to make it fixed firmly. Also the handle has a rubber coating for easy holding.
