Well, my perspective isn't escaping from an urban environment. It is based on hunting, camping and fishing in places where, guess what, if something goes wrong you might be there for a few days, assuming the weather doesn't kill you before you get out on your own or get found. I think, nay, KNOW I need to be prepared for that, anything else is irresponsible and delusional.

My choices are very similar to the knives carried by woodsmen in this area 200-300 years ago (although, I will admit to having replaced the patch knife with a SAK and/or multitool, and the hatchet with a small bow saw), who operated on exactly the same principle. If you aren't going to be able to crawl home by night, be ready to spend the night. Short of the metal-on-metal (not planning on being mauled by a cybernetically enhanced coyote) or metal-on-brick (nor getting mugged by a golem), the way I use a "hunting" knife is exactly as you have described a "survival" knife. The only knives I baby are my really good kitchen knives, my field knives don't live a tea party life, far from it.

As for what I can or can not "deny"... The Project I's blade isn't quite perfect, but it would do. A number of spear point blades were used by traditional outdoors men and still are by their modern counterparts, and even broader and thicker designs of double edged blades (as opposed to daggers and dirks- double edged knives that resembled shorter, sharper Roman gladii were in common use in the outdoors through much of the 1800s and before), even if my personal taste might run to the PII or the Sables.
