I guess somewhere around 4-5 inches long when closed and about 50 to 150g.

I`m not exactly a knife expert and defintly not when it comes to english terms for details, so I`m just looking for a bunch of suggestions, I guess. I can`t find much in this range, probably cause I don`t know where to look. I`ve looked a bit at the Tops stuff, but I won`t be able to try them. I`m sure there`s a bunch of stuff out there that I haven`t heard about.

Most important is that it`s something that can handle being used. I guess any knife could cut a seatbelt, so I`m looking for something that can handle both chooping wood(with help from something to hit it with offcourse) as well as some crow bar style action for doors, hatches, cutting some metal or worst case scenario, stuck limbs.

I guess plain edge would be fine, unless someone has any suggestion for why it would be a bad choice.
