You're attracted to it because it appears useful to you. It is a useful knife. I have two of them that serve me well in the field. One is the orginal Catt 225Q, but I had to replace the guard, handle and tang with brass and new leather washers. The other is one of the Ontario rubber handled ones. I like this one you have shown us.
Very interesting article in a recent Knife World magazine about this knife and whether or not it was a really a 'quartermaster tool' or a real fighting/utility knife. Best evidence I read: Real US Army quartermaster troops had access to real pry bars and hammers. The military would never issue a knife with all it's potential for sick-calls to do the work of a pry bar. Just think on that a bit. And then think of all the photos around from WW2 showing this knife at the side of fighting men. And as I recall, the production numbers just didn't add up... there were far more of these knives made than there were quartermaster troops to use them. Even if they broke every other one opening crates.
It is not a hunting knife; I would not attempt to gut a deer with it. But it will slash, cut, dig, pry, hack and hold up well to that use and abuse. Isn't that precisely what a fighting/utility knife should do?
Buy one and post us a review of it!
