This is just a WILD guess.
Here is a link to a Google book entitled THE OFFICIAL JOURNAL OF THE REGION OF DUSSELDORF: 1846.
Best I can make out, it appears to be something about a "Federmesserfabricant" (pen knife maker)
in Merscheid named Daniel Butz who wants to do something with a "steam machine".
Maybe he was part of the cottage industry in the region at the time who made knives under contract with a larger firm. in this case being H&R Boker. In 1909, evidence was presented that showed that 75% of knives made in Solingen were manufactured using the cottage industry structure. In the mid-to-late 1800s, one could assume that the percentage was much higher.https://books.google.com/books?id=Nxs_AAAAcAAJ&pg=PA320&lpg=PA320&dq=Daniel+Butz+Merscheid&source=bl&ots=617PpNiICO&sig=hmJ2YT4BTtimK2Z0urBMQwM2rt4&hl=en&sa=X&ved=0ahUKEwjCqMzX38jLAhWBVyYKHSa3B5MQ6AEIIzAB#v=onepage&q=Daniel%20Butz%20Merscheid&f=false
Perhaps Daniel Butz was the specialist who forged blades for H&R Boker. Perhaps he stamped his name at the bottom in addition to the Boker tang stamp in order to ensure that he was properly paid by the assembly factory for his work.
All this is pure conjecture of course, but the evidence is certain that there was a pen knife maker in the Solingen vicinity by the name of Daniel Butz!
I also saw a mention on a genealogy website of a PETER DANIEL BUTZ, born in Solingen July 20, 1797.
Could this be the same guy? I do not know.... He is in the right geographical location and is of the proper age.
THIS Peter Daniel Butz was the son of Johann Peter Butz and Anna Catherine Koch.
