`ends of the spoon 110 and fork 140 can slide together and
`illustrated embodiment , the outer edges 145 of both outer
`lock in place . A low profile interlocking mechanism is used
`tines 144 are chamfered so that both outer edges 145 can

`In the illustrated embodiment , as shown in FIGS . 1A and
`separately .
`1B , a safety feature is that when the spoon 110 and fork 140
`FIGS . 1A and 1B are top perspective and top plan views ,
`are nested , the tines 142 , 144 of the fork 140 do not extend

`the tines 142 , 144 do not extend beyond the end edge of the
`position . In the illustrated embodiment , the fork 140 is 25 spoon 110 when nested . As shown in FIG . 1A , the bowl
`portion of the spoon 110 is slightly wider and longer than the
`nested over the spoon 110 .
`As discussed above , the spoon 110 and the fork 140 can

`The handle 146 of the fork 140 will be described with
`described below . FIGS . 4A and 4B are top plan and per- 30 reference to FIGS . 4D - 4H . The handle 146 has a pair of rails
