Stainless Grade

Field Study 001: A Coin. The Original Experiment.

The Idea: Round, flat, and coin-like. A center cutout for pinching and rotating. Stepped levels on one face. A smooth ramp on the opposing one. Contrasting perimeter treatments. Hefty enough to feel substantial, but not so much that it pulls down your pants when pocketed. Solid. Silent. A hand tool for the mind.

Two grades of Stainless Steel:
303: Excellent general-purpose stainless, often chosen for its machinability and value.
316: Higher corrosion resistance, particularly against chlorides. More expensive and more difficult to machine.

Objective Qs: Does anyone care about this thing, in general? If so, then do premium materials justify the added expense?
