Rat Cutlery

What are some good Survival/Tactical knives?

I live in England and I would like to buy a survival/Tactical knife that I can depend on.
I like the Rat Cutlery RC-4 and the R TAK 2 *BUT* I would like a knife that won’t rust (UK Survival=rain:) and one that is strong.
Once again it would be a knife I can trust my life with considering…
Very wet in UK (rained loads the last few weeks-and it’s summer!)
It must be able to perform as many survival tasks as possible and be a good defensive knife if needed.
I don’t really want to spend more than $150 – $200
Thanks!
