Invented in the late 1890s by a Swiss surgeon called Karl Elsener, whose key innovation was to make use of the same spring to put a blade at either end of the knife. It must be the ultimate boys toy (if you ignore a Lamborghini) as well as being genuinely useful. Anyhow, I’ve had one for ages, and I’m not sure how half the household jobs would get done without it – this version even has a pen and a pin in it.
