A Wuest type herringbone gear, invented by Swiss engineer Caspar Wüst-Kunz in the early 20th century, is a type of herringbone gear wherein "the teeth on opposite sides of the center line are staggered by an amount equal to one half the circular pitch".{{cite journal|last1=Daniels|first1=Fred R.|title=Producing Large Herringbone Gears by the End-Milling Process at the Woodward Machine Co's Plant in Wooster, Ohio|journal=Machinery|date=September 1921|volume=28|page=1|url=https://books.google.com/books?id=2IhNAAAAYAAJ&q=Wuest+type+herringbone+gear&pg=PA1|accessdate=18 September 2017|ref=Machinery Vol 28}} This staggering of the two rows of teeth causes the gear to wear more evenly, at the slight cost of strength.{{Cite book|url=https://books.google.com/books?id=VenNAAAAMAAJ&q=Wuest+type+herringbone+gear&pg=PA29|title=Industrial Engineering and the Engineering Digest|last=Kent|first=William|date=1912|publisher=Industrial Engineering Publishing Company|language=en}}
