Why is the mashing plate of the potato masher made narrower and rounder than ordinary tools?
Since the pressing plate is small and round for a potato mashing tool, one might wonder what kind of use this shape was designed for.
It is designed to fit directly inside round canned food tins, allowing ingredients like corn or tuna to be mashed right inside the can.
While kitchen tools with wider surfaces are generally more convenient for handling large quantities quickly, Kajidonya's potato masher has a pressing plate shaped to be narrow and round.
This small head is sized to fit snugly into the diameter of round canned food tins such as tuna or corn[1]. Contents can be mashed directly inside the can without transferring them to another bowl, reducing cooking steps and saving unnecessary dishwashing.
The 18-8 stainless steel used for the body is a kitchen-grade metal material resistant to moisture and salt, making it less prone to rust[2].
hmmm, the detail of sizing it to fit a canned food tin held in the hand rather than a large mixing bowl saves small daily efforts.

The specific outer diameter dimensions of the head or the minimum can diameter it fits stably have not yet been confirmed.
