手腕式

Mnemonic symbol: a baseball glove. Sherlock Holmes (sh) is trying out his new baseball glove (手) in the outhouse's living room (ou3).

式 = 工 + 弋 : I'll use a specific style as mnemonic symbol: 哥特式, gothic.

Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.
