Spey Blade Info
Spey blades are a type of clip point blade which has a very obtuse angle on the clip part leading to a very short-bellied blade almost resembling an oyster-shucking knife with a portion clipped out of it.
This blade type is quite uncommon and usually only found on multi-blade stockman or trapper-type knives. The blade was originally used for neutering or "speying" livestock or animals. It is now rarely seen or really used aside from being found on the aforementioned knives. It is almost never seen on single bladed knives as a primarly cutting edge.
