刀刺

刀 = ㇆ + 丿 : Mnemonic symbol: 刀 looks like a cleaver (while 刂 looks like a kitchen knife).

Don Quixote (d) serves his good deed of the day in front of the aorta (ao1). In order to feed the people, he uses a plow (㇆) to dig up bananas (丿), and cuts them into slices with a broad cleaver (刀).

刺 = 刂 + 朿 : The King of Chu (c) got a thorn (刺) stuck in his chest, and he cannot pull it out because it broke off and the tip is deep under the skin. He has no other choice but to use a kitchen knife (刂) to cut it out in the space station's bathroom (Ø4), but he slips and accidentally stabs himself (朿).
