A Venn diagram with the caption "Nothing to see here, folks, just a very normal venn diagram".
The diagram shows an intersection of three circles. The top shows a knife, the left shows butter, and the right shows a fly.
Intersection of top & left has a butter knife.
Top & right has a Japanese kunai.
Left & right has a butterfly.
The intersection of all three has a butterfly knife.
Weirdly, the kunai shows up when you Google for "fly knife". But the word "fly" is never mentioned on the kunai's Wikipedia page.
it's just a knife that google thinks is kinda fly, not an official name or anything
The word fly knife never showed up in Naruto.
Ackshually, the kunai is known as the fly chef knife to no one, anywhere.
