Spey ( Spay ) blades

[Grumpy]

I couldn`t post these pictures in the relevent topic for some reason so have posted them here. These are Case pocket knives with `spey` blades - In the case of the Case Medium Trapper it is the blade at the left and the inclined blade on the larger Case Trapper.
`Spey` blades are used to spay - ie castrate - smaller stock animals such as sheep ( although they can be used for cattle ) and are commonly found in British, German and American `stock` knives.
