I'm looking for NH Laws regarding Bowie/Survival style knives.?

A knife such as a Cold Steel Trailmaster or an Ontario RTAK II.Will be used in camping ,backpacking,hiking etc..Transported in my vehicle at times.The closest example to an illegal knife in the laws were a dagger or dirk,though no specifics on these type of knives and they do run big with a 9-10" blade.I really want to know the legality of owning using one in NH before I purchase one and have it confied.
