I found trainer chopsticks at Bed, bath and beyond. They were full sized but had the spring hinge like a clothse pin. However, my 18 month old, having only used regular chopsticks previously looked at them and immediately pulled them apart - I assume because it didn't make sense to him that they would be joined.... So we just keep giving him his daddy's chopsticks. So far he just stabs things with them, but he does hold them correctly sometimes.
