Snap on filet knife?

[ryanhewitt]

I acquired (2) what appear to be filet knives off local Craigslist. They say snap on YA150FKNF. Anybody seen these before? I've searched the Internet and haven't seen any.

I'll try and attach photos but I'm on my phone.

If this is in the wrong area, please move.

Thanks in advance.
