Yes. The weight of a knife doesn't make or break anything. I usually have a fixed blade in the pack and a folder in a pocket. Very rarely have a multi tool when backpacking anymore.
I like knives. Certainly don't need both, but it is nice having the right tool for the job.

I often have an EDC folder in pocket, fixed blade on the HPG kit bag or belt, and processing knife like the OE Razor in my kill kit. Could get by with any one of them, but I like knives.
