I really like the saw on my gerber legend (original version - I've heard the quality control has gone down in more recent runs).

The reason I really like the saw is that the saw is whatever I want it to be. The tool has an adapter that takes a standard jigsaw blade, so it can be replaced easily. I usually put an aggressive wood-cutting blade in there, but have been known to carry finer blades if I'm working around metal a lot in the lab. I EDC'ed the legend for several years and it's still my go-to when I need a multi-tool.
