It makes sense you sharpen a knife with ceramics. That's why I like a wood handled hawk with a blunt back edge for smashing toilets.
I was reading a really interesting book called Mantrapping by Ragnar benson last night and you would need a knife capable of batoning for most of those traps.
Other than wire though thats all you need. I am definitly getting his other book survival poaching.

Ragnar was a merc in africa in the 70's and had the opportunity to use these techniques.
You NEED a knife that can take some abuse to be able to stand up to hard use and be sharpened in the field. I notice that there are a LOT of S30V survival knives which to me is silly. S30V is a great steel for an EDC but you want something you can sharpen on a rock or simple stone if you are out in the boonies. No matter how good your edge retention is it will need to be resharpened especially if you use it hard.
