I'd have to say despite its weight, I purchased the ST300 partly as an outdoor survival tool. The tools are slightly larger and I think it would be easier to clean than my Wave also. It sits in the glove box most of the time until I go hiking when it becomes part of a larger system, which incorporates a medium size fixed blade.
I originally bought the Gatco Scepter 2.0 sharpener as part of that system. But its fits pretty neatly here as you can see and offers the ability to sharpen serrated blades and has its own fire starter. The diagnostic torch I included mainly because I get them very cheaply and they have a long shelf life. I may swap this out upon arrival of a super cheap, super bright, AAA pocket torch I have on order.
