Two businesses in Stillwater are in a dispute over the lawn game hammerschlagen, the latest squabble over the rights to hammer nails into stumps for fun.
WRB Inc., which does business as Hammer-Schlagen, this week sued the Lumberjack Company, which operates a bar and restaurant in downtown Stillwater, alleging violations of its trademark and trade dress.
The case follows a similar dispute earlier this year with a Chaska brewery and other cease-and-desist requests nationwide. All highlight the tricky business of trademark enforcement and the provenance of a nail-and-stump activity often associated with Oktoberfest, beer and German heritage.
WRB owns the intellectual property, including the name, logo, slogans and "trade dress" associated with the game. Hammer-Schlagen, or hammerschlagen, involves driving nails into the perimeter of a cross-section of a cottonwood tree stump using a cross-peen hammer.
The game, regularly played while drinking, is sometimes mistakenly thought to have originated in Germany in the 1800s. But hammerschlagen was created by Carl Schoene, who emigrated from Germany to Minnesota with his parents in 1957.
Schoene originally called the game Nagelspiel, after a children's toy in Germany.
He and his parents offered the game at their family restaurant, the Gasthaus Bavarian Hunter near Stillwater, as a way to increase beer sales in the late 1960s.
While there is evidence that Germany has long had a custom of hammering nails into wooden objects as a competitive activity, Schoene and his father-in-law, Mike Wlaschin, developed and codified the set of rules and materials now called hammerschlagen that is commonly used in the Upper Midwest and at German cultural events across the United States.
