I buy the knives by Old Hickory, Ontario knife and some from the Hudson Bay Company all the time at yard sales and junk stores for anywhere from $.50 to $3.00 each and recycle them into fine working liner locking folders and an occassional lock back.
I like the steel in these knives and they perform well for an EDC. We started doing this because it is hard to find a high quality locking folder in high carbon steel anymore these days and it is much cheaper to recycle these old blades than to buy bar stock and mess with heat treatment. I also like the Russell Green River knives and have used them with great success also in locking folder projects. These seem to be harder blades to me over the others I mentioned above. I probably prefer these Russell blades over the others. With water cooling you can reshape these with no damage to the temper or hardness of the steels. I would think they would be excellent camp knives, skinning knives and food prep knives.
I know one of my counter part backyard knife mechanics over at our homepage uses them quite a bit for his project knives also. In fact he just did a friction folder using one of them.

But there are many more there if you search it out. These are pretty good blades and they do cut well once sharpened up correctly with a nicer edge gemetry. Some of my hand made wood carving knifes are this steel also.
Only thing that comes to mind for these knives is the oxidation problems associated with this steel. Slicing acidic fruits and veges can have a detrimental effect on the edge pretty quickly with this steel and so can excess moisture as someone already pointed out. But with some care and a good sharpener this can be worked around easily enough.
Most of the ones we use are blued using the vinegar bath recipe to turn the whole blade a uniform color giving it a head start on the patina that these steels are famous for. You will notice in the links that my friend Dirk, AKA OUPA did this to his blade giving it that uniform blueish color.
EDIT: Here is the recipe we use if you are interested. This does nothing to protect the blade per say, it just makes the oxidation that occurs naturally with this steel less noticed by uniformly coating the whole blade. Also, this can't be done with the handle on it so if that is the case you will have to resort to cutting meat and coating the blade with it all over to get a similar effect.
Normally when making a blade of 01 or 1095 or some other high carbon steel blade like even an old recycled one such as an Old Hickory, or Ontario blade you can:
shape and finish off your blade, then clean well with acetone.
Warm vinegar in an old frypan with the blade in it.
When the blade starts to fizz you keep it at that temprature.
Turn the blade around after a minute or so.
When both sides have turned a uniform black color, remove the blade and wash with dishwashing liquid and a coarse sponge.
After this bath described above they look something like this finished friction grip locking folder by my friend Dirk Potgieter:
