Just out of idle curiosity, I looked up Edward Preston's 1909 catalogue. They list 20 different styles of chisel handle, most of which were available in 9 different sizes, ferrules from 1/2" to 1" by 1/16" increments. (The boxwood handles were available in Best Boxwood and in Best Hard Boxwood - not sure how much of a difference there was, except about 10/- a gross!)
That does go some way to explaining one of the advantages of vintage over most modern chisels - better balance because the handles tended to be selected to match the blade size better, rather than all blade sizes being inserted in one size of handle. That tends to be especially noticeable with the smaller blade sizes.
