I’m in love. I just discovered my new favorite kanji. The simplicity, the straightforwardness, the sheer pictorial common sense beats those unconvincing explanations about how 目 really does look like an eye, 日 like the sun, and 木 like a tree, and 女 like a woman (ok, they may be on to something with the last one). And this miracle kanji is kannuki (かんぬき), meaning a “bolt” or “latch” (Also refers to a 2-on-1 wrist-hold technique in some martial arts).  Brilliant.

==> 閂

See the resemblance?
