When I took pics I thought the long blade tip was just worn, but I see now that the last fraction of the tip appears to be broken off.  Exterior shows dirtiness in the cracks and blades have age use and some black build up on them.  I have not cleaned.  I am not a knife collector, but got a large lot of about 200 in a bulk buy.  Please ask questions on this knife if I did not explain something well or the pics need more clarification.  I think this is still a cool old KEEN-KUTTER and someone could likely clean it up.
