Böker Plus Subcom 01BO610 Friction Folder pocket knife, Chad Los Banos design

The Böker Plus Subcom 01BO610 Friction Folder is, as the name might already suggest, a friction folder pocket knife. This means that the knife hasn't been enhanced with a hard lock to keep the blade open. Instead the knife has a sort of long front flipper you hold in place yourself as you use the knife. As such you can make sure the knife doesn't close, even though officially the knife hasn't got a lock. As a result the Böker Plus Subcom Friction Folder can be carried in most places where locked blades are forbidden.
