A knife includes a metal blade having an integral tang, the tang having a tang end and being a flat bar shaped to carry a handle, a plastic handle having an handle end defining a well surrounding the tang end, and a metal end cap comprising an integrally formed plug section. The metal end cap is attached at the handle end to positively fit the plug section in the well. The plug section has a plug end facing the tang end and defining a recess in which the plug section encloses the tang end in a positive fit. Also provided is a method for fixing the metal end cap in the plastic well at the handle end of the knife which comprises the step of exciting the metal end cap with ultrasonic energy while inserting the metal end cap into the well to thereby plasticate the plastic in the handle. |
