Although records dating to the 1600s refer to spring scales for measuring weight, the earliest design for such a device dates to 1770 and credits Richard Salter, an early scale-maker.
I wish we could pay someone to accurately weigh an item, instead of having unreliable hand-weighing. If I have something that weighs less than 2 lbs, for example, I have no way of telling how much it actually weighs. Aside from the handful of hand-crafted super fancy scales that some people have in game, could we get a method of weighing objects by paying to use a scale in a grocery/general store or a dedicated weighing store?
