couple of questions
1) what is the "spey blade"?
2) if they are using other brands of knives and putting the Case logo info on the blades - are they grinding off the other names or "China" and just how do they get a stamping on the blades - I guess I figured at the factory they logo work was done before the blade was assembled and most likely with quite the machine. Wouldn't they have to take the knife apart to get the logo to fit? That'd seem like more work than what it's worth to me.
Oh, and also on this one - there is the same logo on all three blades - don't they just stamp one blade?
Good questions - so much to learn!
1. The spey blade has a curved shape near the end of the cutting edge, designed to slice without puncturing (it has no sharp pointed end). Typically found as one of the blades on stockman and cattle knife patterns, they were designed for “neutering” and other veterinary tasks on farm animals. Some makers etched the words “For flesh only” on spey blades. You will find similar shaped (but longer) blades on trapper patterns, designed for skinning animals. Again, slice but not puncture. See here for examples of knife blades, found here in AAPK Research

2. Counterfeiters usually take the knife apart, to make it easier to grind off the old stamps and apply the new (fake) stamps. The process of grinding off the old stamp and buffing the tang is called “shaving” the tang. The original stamps were applied by the manufacturer before the blades are tempered/hardened. Counterfeiters use what is called a “cold stamp”, which means it was applied after hardening. There are subtle differences usually detected by a trained eye, either in the stamp itself, or the metal missing from the tang. After making the alterations they re-assemble the knife. Sometimes you can tell the knife has been apart. Sometimes close examination will reveal the blade’s tang is now narrower than its backspring - a sign the tang was “shaved”.
Depending on the manufacturer, older knives were sometimes stamped on all blades at the factory. Some counterfeiters try to fool the buyer by imitating this (or they’re so enamored if their fake stamps, they get stamp-happy).

Knowing what stamps are authentic and when they were used is part of being able to detect fakes.
Counterfeiters often take a $20-$50 knife and try to make it look like a $200+ knife. Sometimes they get a knife someone re-handled simply to repair it, or just to put something different on it. The seller will misrepresent it as something it’s not. They seldom fake a newer knife, but may try to turn a newer one into an older knife, more valuable to a collector. It’s all about the money. If you’re not sure what you’re buying, don’t!!
