Ok,no Tiwantainium/Chineese wonder blades please.
Lets talk about real working blades.I tend to carry four different blades in my backwoods kit,I bought what I could afford and what fit my needs best,you might find different blades suit you better,let's hear about them!
In my kit there is an Indian military ghurka khurki,
A Buck 110,
A Buck General,
A Buck Caping knife.
Also a hatchet and a leatherman multitool and a dozen exacto knife razors in a paper sleeve,but they're not really knives,but they're in there because I use them.
Now this is my camping box,the daily outing box is far different!
it only has a K-bar Marine fighting knife and a small case knife.
What you plan for changes things you see,then there's the fishing kit,it has a fillet knife and an air force survival knife and again with the razor blades,only two.they wipe off well.
Then there's my urban kit,it has a leatherman and a spyderco in it.I've opened neither in ages,but they are there.
Now you're looking at this and thinking:
"why can't this n00b choose one general purpose knife"
I'll tell you why.
ever try to skin a deer with a "Rambo"knife and do it right?ever try to cut tent stakes with a pen knife?
ever try to cut kindling with a sheath knife?that's why.
It might weigh you down,but the right tool for the right job is priceless!now let's hear about yours and why you pack em'.
