Gnomes and redcaps may look similar to the untrained eye but really they’re easy to tell apart.
Does the little chap with a red hat have a fishing rod, a shovel or wheelbarrow or some other agricultural implement? That’s a gnome.
Does he have a pike; is he trying to bite your face off? Redcap.
There are those who will try and tell you that redcaps are just gnomes who’ve been on the Tennent’s Super Strong but that’s just anti-gnome, anti-Scottish propaganda.
It can admittedly be tricky for laymen to quickly spot the difference between a hoe and a pike but the “biting your face off” is a dead giveaway.
