Do you know which maker made this one? Any way to date it?
Stan, there were several makers that made those knives back in the later part of the 1800's, the three premiere makers were Jon Engstrome, Segerstrome, and C. Holmberg, all from Eskilstuna in Sweden.
There's also a set of three different sized barrel Knives at an antique dealer in NYC, the asking price is $1250.00 firm for the set.
There are reproductions being made that run around $50.00 on e-bay.
All of Engstrom's barrel knives are marked 1884 regardless of what year they were made, some believe that was the first year of production, other think it's a model number, I've heard that he only made them for one year, but no one actually knows, but it is an interesting design, and they were (the originals) all hand made.
