Schick Injectors for Dummies — Types D and O These 2 are being consolidated in one page since there was only one razor produced for each type and they also happen to be the first and very last Schick injectors made to date. Type Dadd_link In 1934 the very first injector razor was introduced commonly referred to as a Type D. Prior to this the Schick razors used a blade magazine and repeater. This was the first injector to use an external injector key to load blades.

The accepted date that production ceased on this razor is 2001 and since then there hasn't been any other Schick injectors produced by Pfizer or Edgewell which currently owns the Schick brand. Hopefully that changes sometime in the near future since injectors even the mediocre ones were some of the best safety razors ever made. Variant 1add_link Style 1add_link Key feature is the handle style as seen in the pictures below. This razor is also referred to as a Type O. Produced 1998 - 2001. Clonesadd_link Also of note is the fact that later on that this razor was reintroduced unbranded made by third parties. It was commonly known as an ebarbershop Type O clone.
