well,best make sure he uses slugs instead of buckshot then
only thing youd make of it would be a sieve then
more to the point,im starting to doubt the real usefullness of "ray mears" type knifes for most bushcraft use.
although certainly a good piece of kit i find a smaller and somewhat thinner blade (like the clippers) is easier to use.
they can take more abuse but you might just as well take a small axe out to make up for the loss in sturdiness
thinking back to when my granddad was still alive,he never used a big knife and he did have a lot of experience in the bushcrafty things (poor family in a rural area,sure makes ppl resourcefull)
