The King of Spades shovel's long tapered cutting edge is virtually self-sharpening because the taper geometry causes soil abrasion to wear the steel in a way that maintains a keen bite over time. As you dig through clay and compacted soil, the friction removes material from the edge at an angle that preserves the cutting profile, so the blade stays effective without constant manual sharpening. The tapered design also concentrates force at the tip, which helps the edge slice into hard ground more efficiently than a blunt-edged shovel.
