As if winged eyeliner wasn't hard enough to master, those Insta beauty bods have gone and upped the game.

Just in time for Halloween, there's a creepy new craze sweeping IG and it involves knives being painted onto the lids.

Ladies and gentlemen,'this'is Knifeliner.

The trend involves tiny knives being painted onto the lids, withthe handle of the knife making the wing of the liner.

For the very talented - and steady-handed - there is even the option to have teeny drops of blood dripping from the blade.

Talk about a 'cutting' edge trend. You're welcome.
