Call this irrelevant, but... What has happened to the little hole that used to be on the side of Bic pens? Did it have a function that new Biro technology has made redundant?

Didn't the hole stop a vacuum forming in the bic?? ... I never noticed the disappearance of said hole in the newer (holeless) pens.....G.

Geodhinn is absolutely right! The hole was placed there by Lazlo Biro himself because his pens, designed for mapwork and notes in unpressurised airplanes in the forties would only work intermittentently at various heights due to the pressure differences between the inner and outer tubes, it was also to stop the infamous exploding refill (never got that quite right did they!)
Of course, othr nations got around the "Oh dear, this pen won't work in an airplane" problem by using......pencils! Now which took less man hours to solve the problem?!!
