Claim:
A method of forming an article of cookware, a) providing a vessel capable of containing fluid, the vessel having substantially upright sidewalls, b) forming at least one hole in a sidewall of the vessel capable of containing fluid, c) providing at least one rivet having a tapered head and an adjacent shank portion extending therefrom that is notched at the junction of the taper and shank portion of the rivet, the notch being an extension of the taper of the head, that extends with the outer circumference of the adjacent shank portion, d) inserting the shank portion of the rivet into the hole formed in the sidewall of the vessel capable of containing fluid from the interior of the vessel, e) deforming a portion of the vessel sidewall surrounding the hole to flow into the notched side of the rivet thereby mechanically interlocking the rivet and the sidewall of the vessel, wherein said step of deforming displaces the head of the rivet to be substantially flush with an adjacent portion of the vessel sidewall, f) providing a handle that comprises a flange portion and at least one hole therein, g) contacting the flange portion of the handle to the sidewall of the vessel whereby the shank portion of the rivet extend into the holes in the flange, h) deforming the shank portion of the rivet that extends through the hole of the flange such that the shank flattens and expands past the margin of the hole thereby locking the handle to the vessel.
