I might be jumping the gun, but from the pictures I would say, stay away!
For bushcraft...
Steel:First off, anyone who uses the top grade of 440, ie 440C, will say so, and you don't tend to get that grade in knives of that price, so it is going to be softer 440 A or B, my money is on the former.
Weight/ballance: They are going to be very handle heavy, full thickness tangs and bulky handles. Those without bolsters will be a bit lighter, but probably even more butt heavy.
Grind: Many will not like the idea of the hollow grind. It isn't ideal, but can work. There have been discussions on this before.
If you want a cheap hunting knife to abuse, they don't look bad, better than some...not what I would want for bushcraft, not with all the excellent puukkos out there....and I don't like puukkos all that much
