A place to discuss & share pictures of counterfeit knives. Please be sure to alert the AAPK community if you spot one. Also make sure to ask questions if you are not certain about the authenticity of a knife you are considering buying or selling. There are plenty of great people here willing to help.
The jigging on the bone looks like what was done on the Pakistan "Ole Smoky" line of knives from a few years back. But the fit and finish on your PUMA looks alot better than anything "Ole Smoky" ever put out
I don't know about being authentic, but I zoomed the pics and can see what looks remains of some writing on the blade, some letters and numbers. Above and to the right of the Puma etch.
