If you want to see really misleading marketing...try buying a "quart" or a "half gallon" of ice cream! Or similar products. I think there is one brand of ice cream that is true to the traditional measure of volume.

As for steel, the shop "could" send along some of the floor sweepings to make sure that the customer got the full value of the 1/4-inch stock that they started with to make the knife.

The finished product is what counts, not what is left on the shop floor.

Just my two cents...
