Boker was one of the great Solingen cutlery houses. Probably the greatest.
I wouldn't be surprised to find the actual start date at something more like
1600. Their goods were exported worldwide and new companies were started and
run in other locations under the Boker name as well. Boker was practically
the Stanley of Germany acquiring scads of other companies and products along
the way. I'm not sure if they actually went into garage door openers before
the end, but it's likely.
