The 1958 United States Federal ban on switchblades had a devastating effect on not only American made autos, but also those from Europe including Italy. Every kid in the late 1950s and early 1960s (and throughout time for that matter) wanted a real "spring fired" knife. There must have been some shock and sorrow when young lads received their switchblades in the mail after 1958 only to find out that they had no springs.
Italy never stopped producing switchblade knives, but their market shrunk greatly after 1958. New and old Switchblades are once again quite commonly found in the US.
Enclosed is an ad from 1959 which states "Closes With Lightning Speed"
