Going back to the original debate, I reckon that, without clothes, Ed Stafford tops out but, with clothes on, it is hard to beat the calm familiarity of Uncle Ray. For me, Bear is a little like a firework: flash, pop! and then it's gone.
Perhaps we should judge them by the knives to which they've put their respective names... Things like price, materials, shape and geometry, size and so on might yield a more objective but still representational comparison...?
Read this and thought, “Oh blimey, here we go”. But in reality this is a good way to make an analogy. The Mears knife is the learned tweed dressed gent, capable of being gentlemanly and useful, but ultimately limited in its uses. It’s a wood working knife that‘ll do other stuff.
The Bear Grylls Gerbers are cheap, robust, really capable, and once you get past the awful marketing, and the part serration, very comfortable to use. An all rounder that will cope with a multitude of tasks.
I don’t know who Ed Stafford is, and I’m not bothering to find out.
