While the word "toys" undoubtably is used mainly to describe Birmingham products, I don’t think the term was only used in Birmingham, or that they were only steel. Defoe in 1728 said “ nothing is more evident in trade at this time than that the best knife blades, scissors, surgical instruments , watches, clocks, jacks & locks that are in the world, and especially toys and gay things are made in England and especially London”. I suppose that some might consider toys here to mean toys in the modern context, but I don’t think it likely. John Price Durban in his “Observations of Europe, principally France and Great Britain vol 2” describes the area as “The great toyshop of the world”, as did the Catholic magazine and monthly review, (vol3). Knight, in “Capital & labour” refers to makers of glass toys such as glass eyes.
As to the material of toys, Gill (History of Birmingham) quotes a 1770 Birmingham directory : “these articles are divided into several branches, as the gold & silver toymakers, who make trinkets, seals, tweezers, tooth pick cases, smelling boxes, snuff boxes & filigree work such as toilets, teachests inkstands etc etc. The tortoise toymaker makes a beautiful variety of the above , and other articles, as does the steel, who makes corkscrews, buckles…. and almost all of these are likewise made in various metals.”.
