hoe with long blade at acute angle
鍬 centers on a specific farming tool: a hoe with a long blade set at an acute angle, used for digging or tilling soil.
鍬 combines the metal radical 金 with the phonetic component 秋 (シュウ), suggesting a metal tool whose name is related to the sound 秋. The exact historical development is uncertain, but the phono-semantic structure is typical for tool names.
The left side 金 (metal) and the right side 秋 (autumn) together suggest a metal tool used in autumn for turning the soil: a hoe with a long, angled blade.
For ショウ, imagine a farmer showing off his new hoe: show -> ショウ, and the metal blade gleams in the autumn field.
