what, may i ask would you be using the knives for?
survival?
and what do you mean by survival?

like an all-round/multi-purpose knife?
or just a ready-eddy kind of stab one stab all knife?

if it were just survival, then the knife you had in your hand/pocket would make sense...

very difficult....

therefore i always advocate...one Swiss Army Knife- Matches-and a good light to guide me by... (a lighter can and will let you down)...

from here i can plot...

no offense...just my two cents...
