Our son has included a penknife on hie xmas wish-list and whilst DH thinks it an ideal stocking-filler I can't see the point, nor am I sure it's appropriate for him. None of his friends has one, nor is he in the Scouts...nor even engaged in the kind of pursuits a penknife might come in handy for! DH says it's one of those things active young boys just like to have, and he himself had one by the age of 10...
