Coat of arms of Switzerland specifically on coins and number plates. A number of regulations passed along with the new flag law, also in force from 2017, restricted the commercial use of the Swiss cross. Dubbed the "Swissness regulation" ("Swissness-Verordnung"), these changes were originally proposed in 2006 by national councillor Jasmin Hutter and state councillor Anita Fetz, and eventually implemented in five separate regulations. Numerous exceptions were granted to companies who have historically used the Swiss cross, such as Swiss army knife producer Victorinox (uses the federal coat of arms as company logo since 1909).

Swiss Army knife knives lighter. Previously these separating layers were made of nickel-silver. The martensitic stainless steel alloy used for the cutting blades is optimized for high toughness and corrosion resistance and has a composition of 15% chromium, 0.60% silicon, 0.52% carbon, 0.50% molybdenum, and 0.45% manganese and is designated X55CrMo14 or DIN 1.4110 according to Victorinox. After a hardening process at 1040 °C and annealing at 160 °C the blades achieve an average hardness of 56 HRC. This steel hardness is suitable for practical use and easy resharpening, but less than achieved in stainless steel alloys used for blades optimized for high
