Tinker's Tools is the new Longsword?

A True Tinker (one who fixes tin and brass pots, containers, usually a little bit of this and that) is different from a Jeweler (one who makes jewelry - fine chains and small pieces, lockets, and as the technology changed small clockworks) is different from a Gem Cutter (Minerology + Geometry + Materials Science + a bit of finesse to get the most out of a raw product) is different from a Sculptor, etc.

As used by Gnomes, Tinker is the modern sense - one who futzes around with little doodads and devices. That kit is more akin to the Jeweler, particularly if a magnifying loop is involved. The classical Tinker folds into the Silversmith - softer, finer metals, with a strong focus on housewares, in addition to the metal art pieces.

I suppose this is a lot like calligraphy & forgery - the specific pieces in the kits overlap, but your proficiency - your specific training in use, has a different focus. You both need precision tools, need to be aware of how pieces fit and move, but one of you is focused on optics, the other on using a mainspring.
