Spear
The spear radical and the spear kanji are the same!
Spears are spears. It makes sense!
む
ほこ
None
You take this spear and stab it into a cow. "MOO (む)!" it cries. The cow bites the spear out of your hands and stabs you back. "MOO!" you scream.
How do you like it? Don't stab cows with spears, you monster.
