For the purposes you listed, I'm going to have to agree with Blerv and Iris223 that a Tasman Salt would probably be optimal. I don't know if it's out yet, but the Byrd Hawkbill costs less, has a blade similar to a Tasman (but with a 50-50 finger choil which in my experience is a really nice feature to have for certain kinds of cuts), costs less, and has a steel that while not as rust-resistant as H1 (H1 being rustproof more or less) should be fine, though I would try to rinse it if it gets exposed to chemicals regularly (soil and water should be fine typically). I would take a serrated hawkbill any day of the week for cutting straps, burlap, opening bags, pruning plants, etc.
I drink, and I cut things.
