The Bradshaw Blades Pocket Guillotine is going to be a downright nasty little last ditch self-defense option. The images shown are of the prototype and there will be changes when it reaches production.
The Pocket Guillotine is essentially a single finger knuck with a cutting edge. It is made from titanium. The edge is chisel ground and carbidized for edge retention. The production Pocket Guillotine will have additional contours for comfort along with a lanyard hole and bottle opener.
