In 1891, Karl Elsener, then owner of a company that made surgical equipment, set out to manufacture the knives in Switzerland itself. At the end of 1891 Elsener began production of the "Modell 1890" knives, in direct competition with the Solingen company. He incurred financial losses doing so, as Wester & Co was able to produce the knives at a lower cost. Elsener was on the verge of bankruptcy when, in 1896, he developed an improved knife, intended for the use by officers, with tools attached on both sides of the handle using a special spring mechanism, allowing him to use the same spring to hold them in place. This new knife was patented on 12 June 1897, with a second, smaller cutting blade, a corkscrew, and wood fibre grips, under the name of "Schweizer Offiziers- und Sportmesser" ("Swiss officer's and sports knife"). While the Swiss military did not commission the knife, it was successfully marketed internationally, restoring Elsener's company to prosperity.
