Let me pile on. Take the largest most obnoxious blade you have, hell take everything you've got, throw in a few guns for good measure. If you can find a surplus army helmet and wear it all weekend and throw in a bullet proof vest and a tactical vest just for good measure. See if you can't find a copy of old copies of solider of fortune magazine and break them out and read them at random times. Put all your gear in a pack and wear it all day everyday while your out. Make a copy of this thread and when they ask you why your all geared up, show em the print out of this thread.
This will solve your problems with these ignorant political correct types, next time you go camping you won't have to worry about what knife to bring for fear of ridicule because your uptight, anal retentive, croissant munching, internationalist, pointed head, academic types. Dolt's the lot of them. Don't bow down to these ingrates and curb your legitimate right to carry and use these tools. Just bring what you want and carry/use it like you normally would, its your vacation too so enjoy yourself and don't worry about these fools.
One last thing you reference these folks as friends, maybe you should question who you deem as friends. I try not to make it a habit of associating with people who refuse to exercise common sense and logic by operating in the world of possibility instead of probability. If I need to clarify this for anyone let me know and I'll reply.
