I very strongly recommend learning how to put, and maintain, a basic edge on your knives. Try youtube; there are roughly a bazillion sharpening vids on there. Stick with the simplest ones.
Like stereo equipment and bicycles, you can spend as much or as little as you like on knives and still get something that makes noise or gets you from Point A to Point B. My sincere recommendation for almost anyone is the Becker line, manufactured by Ka-Bar. They're very sturdy, well-thought-out designs, made in the USA with a solid warranty, and they're affordable. If you're willing/able to spend a couple hundred bucks or more, naturally I welcome you to take a look at my work, other handmade/custom makers, or companies like Survive!, BRKT, Fallkniven, and so forth.
If you're on a tight budget and simply don't want to learn how to sharpen, just get you a set of steak knives from the Dollar Store and an inexpensive Coughlan's folding saw from WallyWorld. Possibly a machete if you may encounter a lot of tall grasses or thick brush. Throw the steak knives away when they get dull. The saw will outlast you if all you do is saw wood with it, and honestly a machete doesn't really need to be razor sharp to clear brush (although it helps). Total investment, about $30.
Terrio Handmade Knives
Growl model. Mr Terrio hosts a knife makers forum right here in
BF and he has his own website. I don't think even one of your "Non BBQ" weekends can ruin one of his blades.
Thanks for the mention
Any knife can be ruined, of course... it mostly depends on whether one uses it as a knife, or as a screwdriver/cold chisel/prybar/concrete block smaller-maker, etc. Also, my website is down for the foreseeable future. The subforum is alive and well.
