Others may disagree; but IMHO the 25" is *the* ultimate all-round khuk. It'll do everything; it's perfect as the "machete substitute" (only it's better at that kind of work than any machete I ever used...); it'll happily chop, limb and split lumber. You can use it as a wedge, a prybar or, indeed, a sword. It has the strength, because of the narrowness of the blade (the edge bevels are short, therefore thick; it's actually stronger, IMHO, than many of the wider, heavier khuks for this reason. The Kobra *isn't* a sirupati); it has amazing balance, which means more cut for less effort, and the extra length is mechanical advantage in action.
I defy anybody to break one, except by outright and outrageous abuse; and even then, you won't find it easy.
In my opinion, the 25" Kobra is the only khuk you'll ever need. Some designs may perform specific tasks as well, possibly even better; but no khuk - no edged tool - does so many jobs so well.
Get one, and see for yourself. You won't be sorry.
