| Abstract: |
A compact and convenient chopstick system includes a first elongate member having a proximal end and a distal food engagement end, the member further having an outer lateral surface and an inner lateral surface comprising engagement means at the distal end. At the proximal end of the inner surface is a male journal surface including a transverse pivot channel and a transverse rotation-limit surface, and a U-shaped channel within a distal side of the journal surface of the inner lateral surface. The utensil further includes a second elongate member having a proximal end and a distal food engagement end, the member further having an outer surface and an inner surface comprising engagement means at the distal end and a female journal surface, complemental to the male journal surface of the first elongate member, including a transverse pivot channel co-linear with the channel of the male surface, and a transverse rotation limit surface complemental to the rotational limit surface of the first elongate member. The second member also includes a U-shaped channel within a distal side of the journal surface of the inner surface of the second elongate member.

Having described my invention what I claim as new, useful and non-obvious and accordingly, secured by Letters Patent of the United States is:
1. A utensil for a compact chopstick system comprising:
- (a) a first elongate member having a proximal end and a distal food engagement end, said member further having an outer lateral surface and an inner lateral surface comprising:
- (i) engagement means at said distal end
- (ii) at said proximal end, a male journal surface including a transverse pivot channel, and a transverse rotation limit surface; and
- (iii) a U-shaped channel within a distal side of said male journal surface;
- (b) a second elongate member having a proximal end and a distal food engagement end, said second member further having an outer lateral surface and an inner lateral surface comprising:
- (i) engagement means at said distal end;
- (ii) at said proximal end a female journal surface, complemetal to said male journal surface of said first elongate member, including a transverse pivot channel, co-linear with said pivot channel of said male journal surface, and having a transverse rotation limit surface therein complemental to said rotation limit surface of said male journal surface; and
- (iii) a U-shaped channel within a distal side of said female journal surface;
- (c) an axle secured within said pivot channels to thereby pivotally join said first and second members; and
- (d) outward biasing means spanning and secured within both of said u-shaped channels to thereby stabilize said elongate members relative to each other and to also provide a normally outward bias relative to each other to thereby provide an ergonomic response when the members are engaged by the human hand as said members pivot about said axle.
