I have one that I received in a trade. It is the stoutest, "small" fixed blade I've ever held. With it's 4", 1/4" thick, (at the spine), blade, it should be! It's beefed up even more with it's 1/4" full tang! I've had two Model #18's in the past and I would trust this one more under hard use. It's my favorite small fixer especially with the border patrol handle. It will take just about anything you can dish out. Even though it is heavy for it's size, it carries very easily and I can't understand why they aren't more popular.
