The first handling attempt today saw me splitting the blank. Apparently I didn't chisel out quite enough for the tang to fit in the handle.
I timed myself a bit just for fun, and it took me two hours to put a handle on two chisels. That is not too bad in my opinion. Maybe I'll start having some blanks ready for stuff like that at home. Then I could put a handle on a tool while the children were working with me. All of the operations of handling using this method can be stopped immediately without any consequence. So it is a project where it is possible to come and go as one please.
I tried to find out something more about the company that has produced the chisels.
On the chisel itself it says: Garantie C. Steinbach & Co
Which means: Guaranteed C. Steinbach & Co.
According to the homepage of "Kleines Werkzeugmuseum" (small tool museum), the company of Steinbach & Co usually had a mark consisting of a globe with an axe (Globus mit beil).
Sadly that was the only information I could find on that side.
I Googled on, and managed to find some pictures of old bills from the company, but nothing about its history.
My last attempt brought me to this page of a local newspaper (in German): It says something along the lines of: From industrial area to residential area.
Steinbach was apparently the last company in the mentioned area, and their right to use the area ended in 1982 after which the factory was torn down.
It is mentioned that the company manufactured tools under the name : "Stecoge"
If any readers from Germany (or elsewhere for that matter) know more about the history of C. Steinbach & Co it would be very interesting to hear about it.
