I don't hold my knife like a pencil, but I don't understand why it is so upsetting for people to see others doing so. Someone somewhere decreed that there is a 'correct' way to hold a knife - I doubt anyone now knows who, where or why - and all these years later it is used to suggest that people holding it differently is offensive. Maybe they're just doing what the 'non-pencil' people do, which is hold it as we were taught as children, or maybe they just prefer to 'pencil' their knife? Why is it offensive?
Well put, Doodledog
Offensive is a strange term to use for something which evidently makes non-pencil holders feel superior.
Talking with your mouth full, eating with your mouth open is offensive because it’s unpleasant to see, or feel the effects but criticising someone for holding a knife?
Is it because our betters were seen to hold their cutlery in a certain way and aping our betters makes people feel good about themselves?
I don't think it's offensive although I do find it irritating! Less so now because people's table manners have deteriorated rapidly over the last few years fir some reason. Fast good? No 'proper' school dinners, more finger food?
I do think more pressure can be applied holding the knife the 'correct' way rather than like a pencil but I haven't conducted any experiments to find out if that's true!
