Spyderco UK Pen Knife Black.
Spyderco UK Pen Knife Black. 4 1/8" closed non-locking folder. BD-1 stainless leaf shaped blade with thumb hole. The blade is held open by a notched-joint at the knife's pivot. When closing the blade the notch produces roughly twenty-pounds of resistance, functionally similar to traditional slip-joint pen knives. Developed for the UK market where there are strict restrictions about blade locking mechanisms. Black FRN handles. Reversible stainless pocket clip
