The sometimes highly technology-centric climbing styles and techniques developed mainly before the First World War influenced climbing in the Kaiser until the 1960s. In 1977, grade VII climbing was introduced with the free ascent of the Pumprisse by Reinhard Karl and Helmut Kiene on the Fleischbank. In the 1970s and 1980s a whole range of sometimes extremely difficult sport climbing routes were opened in the Kaiser mountains. The most difficult currently is The Emperor's New Clothes route (Des Kaisers neue Kleider, grade X+) by Stefan Glowacz on the Fleischbank pinnacle.
