the oldest tool that still ends up in your kitchen drawer and your nightmares
means A handheld tool or weapon with a sharpened blade fixed to a handle, used for cutting, slicing, or stabbing.
from From Old English 'cnif,' likely borrowed from Old Norse 'knífr' — a Viking import that fit snugly into English hands. The 'k' was once pronounced, but English speakers eventually fell silent on it, leaving the letter to sit there uselessly like a blade in a sheath. Cousins survive across the Germanic north (German 'Kneif,' Dutch 'knijf'), though where the word ultimately came from before that is genuinely murky.
