ABSTRACT:
A dental apparatus or instrument includes a hollow, tubular metal handle, closing members fastened to opposite open ends of the handle, and tool parts connected to the closing members. The metal handle includes a central substantially smooth region and two surface contoured regions adjacent to the closing members. The surface contoured regions include wide grooves in a criss-crossed pattern superimposed on V-shaped narrow grooves in a criss-crossed helical pattern. The combination of the two type grooves gives a sure grip feel to the two surface contoured regions. The closing members each include an attachment portion which tightly interfits into an open end of the handle and which is brazed into the handle.
