The Pharmacy Knife came in regular Cellidor scales, typically in yellow, with Pharmacy Knife printed on the front handle in silver screen print and usually a drug advertising message on the back.
It was, however, also available in regular red scales without advertisements.
Little is known about the history of this model. As noted above, it was probably only sold through the premium sales channel to the pharmaceutical industry for promotional purposes.
