I have for sale here a Cold Steel Chaos Push Knife.  I have three so I figured I should sell one. It has a 5 inch double edged blade of SK-5 steel. Its overall length is 8 inches and it also has two removable skull crushers that fit on each side of the handle. Also included is an adjustable Secure-Ex sheath. This is a really cool knife that is very sharp.  
if you have any questions, feel free to send me a message and I'll get back to you as soon as possible.  THANKS...
