Antique lobster pattern pen knife (internal spring) with Shriners emblem made in Solingen Germany by J S Holler & Co for the San Francisco retailer Adolph Blaich between 1895 and 1906.
Blades show sharpening and light pitting but have good snaps and no wiggle open. A cool piece of pre-earthquake San Francisco history here.
Most vintage pocket knives come unsharpened unless specified or requested.
