If this blade holder could talk -[ HMM ]-

One of a pair of blades in a Neumade Neutaper 35mm film splicer. The U-shaped blade holder carries an identical blade at the rear in a Janus-like arrangement. Both blades trim the splicing tape from the film sides; a punch assembly clears the sprocket holes of tape.

 

All these years, I never noticed the faces hidden in these splicers, but they could say a lot if they were sentient.
