Yes for sure the lever spring scissors started without serrations. These you find 1973-1977. Thank you very much. BR
The super scissors 1977 got the lever system, got serrations and is self sharpening. The period 1971-77 May contain variations. Wenger started the future. BR
So the scissors with lever system were once had plain edges? Wow, I would never have imagined it! You have the best information about SAKs in the entire Web. Thank you very much, regards!
It is the same lever system from the early 70s, Wenger designed this because it is a safer and more durable. In the late 70s it got serrations.
