When was the guillotine film splicer invented?

Razor blades were used to edit video tape in the early days of video editing for broadcast, especially 2-inch quad and 1-inch tape. The cut had to be made on a diagonal to avoid a roll bar. Some people (like mua, aka Jane P) were very good at it. Linear editing was made by dubbing from tape to tape which lost a generation. CMX was introduced in 1971, the first non-linear editing system, and razor blade cutting was phased out. 

A guillotine (/ˈɡɪlətiːn/ GHIL-ə-teen, also US: /ˈɡiːətiːn/ GHEE-, French: [ɡijɔtin] is an apparatus designed for efficiently carrying out film executions by beheading. The device consists of a tall, upright frame with a weighted and angled blade suspended at the top. You'd buy clear sprocketed editing tape for this apparatus at 'Rafiks' store in Manhattan.
