The Victorian era was the heyday of the Sheffield knife industry. They made some of the finest knives in the world, as well as some of the most advanced designs. Among the gentry class, intricate lobster patterns with many blades on both sides of the knife were not uncommon. These blades included pen blades, nail files, button hooks, and reamer blades for pipe stems. Small scissors were not uncommon. Think forerunner of the Swiss Army knife.
Pocket knife scales of this period saw a lot of pearl used as well as some great India stag.
This was also the era of the wharncliffe blade point style. It was a popular blade from the 1890's to the 1920's.
