This thread has made me chuckle!
But OP, I agree with you. Cutlery usage by the masses is a declining art and that is a great shame indeed.
I am often amazed by the lack of cutlery skills of my DS's playmates, with 8/11yos who haven't a clue how to properly cut with a knife let alone hold it properly. I do think it is a basic skill that should be taught by parents at a fairly young age then it is ingrained for life.
