Hi,
I've had two of Dale's knives, with another on order (I gave the other two to friends as gifts after using them a while). Dale makes a great knife. They don't come much tougher - keep in mind these are cut out of the huge bandsaw blades used in lumbermills (that's what Dale does for a regular job - sharpen sawblades for mills). This also means that they hold a good edge - the steel is, for th emost part I believe, L6 - and Dale knows how to heat treat it.
As for the tough part - I've had a short blade (8" smatchet) and a long one (12" machete), and I do believe you could pound these knives into a stump and use them as a springboard (step) without ill effect on the blade. The handles a cast on - they will not come off period. Dale bolts a 1/4" steel plate to the butt so you can hammer with it. If you get it with the paracord wrap the grip is secure.
Very good value for the money, if you don't mind the 6 month wait.
