A few years ago I was trying decide between the "OG'" full sized CE manix and a Millie for uses similar to what you describe. At the time I missed out by a matter seconds as my dealer wound up being out of stock on the Manix and I ended up going with the Chinook III.
The Chinook III's build quality, tip strength and ergos are excellent. Yet on an edc level the plentiful belly and upswept tip wound up being more of a hindrance than anything else, that is unless your processing meat or have to defend yourself. This is also a very comfortable knife in hand.
The Millie is an outstanding allrounder, this is a true utility knife and lends itself well to a vast array of tasks. It's light weight, open construction, high carry clip all add up to a indispensable tool when it comes to working outdoors. Don't over look the SE version either.
If your entertaining the idea of a OG Mini Manix also investigate the Gayle Bradley M4, which is has all but single handedly retired my faithful Mini Manix.
