There are two different types of injector blades. One is the Feather style Artist Club (aka AC) injector blades. They have a blade thickness of 0.254mm and a blade length of 50mm. Schick also makes Proline blades that have dimensions similar to the Feather AC blades. Kai sells Captain blades which are also AC style,
The other style is the original Schick style injector blade. They are also sold under the Personna brand. Both Schick and Personna are brands owned by Edgewell Personal Care. These blades are shorter than the AC style blades. It appears you purchased the shorter blade.
While using the shorter Personna injector blades in the AC style razor might work, the blades are short and are not properly supported on the ends. That might allow the blade to move during use, If the blade does shift, that could cause irritation or even injury. Thus, if you do decide to use the blades in this manner, monitor blade alignment frequently, especially if you experience any discomfort during the shave.
I suggest that you obtain a pack of either the Feather AC blades (various types are available), Kai Captain blades, or the Personna Proline blades. Just make sure you get the ones with or without an injector key depending upon the design of your razor. All three of the blades are manufactured in Japan.
