My Emerson Folder is on me fairly often.
That said I am really a fan of Mora fixed blade knives for general purpose use, and have them in various sizes. In fact the last 1/2 dozen elk I have skinned and processed have all be done with Mora knives:
You can see the Mora stuck in the top of the elk in this pic.
They make a little Mora called the Eldris that weighs almost nothing, that I keep in my chest pack. It goes hiking, kayaking etc. Cool little knife and super sharp.
One that is a folder, that really would make an outstanding "Bug out bag" type knife if the Cold steel Pocket Bushman. RJM got one for me as a gift. I just looked and realized that I don't have a pic on my IMGUR account. Something I need to correct. It is a large folding knife, but surprisingly thin, and pretty handy considering the size. I am not into large knives, but I REALLY like the Pocket Bushman quite a bit and often carry it as a second knife at work.
