All About Pocket Knives

I managed to get my hands on a few of these fine Barlows made by GEC for Charlie Campagna (Upnorth on this forum). These are very limited so if you snooze... They're in my AAPK store now.

Barry -- Did you only want single blades or is that all that was available?

I have noticed that some of the knives/scales have a rating of A,B or C....what is the difference....quality or grade of wood,bone etc.
