They guy I bought this from usually has the 110 autos also
If it is World Class Blades, I would be concerned, as a lot of his knives are counterfeits and fakes/clones.
Note: This is not to say that your 112 is or is not legit.
What's the best way to tell Brad?
Blade is Stamped -
BUCK
112
USA
After the 112 there is the upper half of a circle with a dot in the middle.
It has the heft of a Buck knife, most of the knives they try to pass as a Buck do not have the right weight from what I've noticed
