Rare Kaufmann chisel restoration

I have restored this old and rare chisel made by Heinrich Kaufmann company. Brand Kaufmann K55K is well known for its Mercator knife, bayonets or scissors. But I have found very less, practicaly nothing, about its chisel production. Actually I have found only one image of Kaufmann's chisel. So the design of the handle and logotype is inspired by this photo. K55K means K = Kaufmann, 55 = adress of manufactury: Hochstraße 55, Solingen, K = Katze (black cat was a emblem of Kaufmann brand). If you have some info about Kaufmann's chisels, please leave a comment.
