Here's a very rare antique Glepen Co. USA pocket knife.  This is a unique piece with a push button on the end to open and close the knife.  Hallmarked "Glepen Co Made In USA" on the end of the blade.  It measures approximately 3 inches in length.  It's in good condition; with some signs of age wear and use which you can view in our high resolution photos.  

We have not found another one like this anywhere.  Another great collectible piece from Power Of One Designs.  Visit our shop categories for more unique vintage and antique items.
