I always have a fixed blade on me, I wouldn't go anywhere without it. Who knows what trouble you might get into in the wilds. It's always good to have for protection as we'll, if you can find a nice lightweight knife it might be worth it. I usually carry a Remington fast on me.
On the other hand it's always useful to have a multitool maybe if you could also find a lightweight multi you could pack that as we'll.
