There are an infinite number of ways that it can potentially be defined, but there is only one question to life: "Are you going to deal with reality?"
In accepting reality, we as White men, to the extent that it is legal to do so, should be in possession of the means to defend what we are not willing to compromise. Aside of course from utilizing our brains, and those without a conceal carry permit, you may come to regard it as useful to carry a knife with you. Without doing so, you are saying that you are willing to submit to the outcome of unfavorable circumstances that surpass the abilities of your fists. A knife provides you with options.
My recommendation costs roughly $50.00 to $60.00 and can be purchased from most Wal-marts. It is the Kershaw 1660BLKW.


You barely click the knob that opens it, give a slight flick of your wrist, and you can have it from your pocket and to ready to go in about 1 second. It is a very thin and sleek knife that you can carry without people knowing it and without looking like a retard who needs a bowie knife to go to the grocery store.
I have owned many different knives. This one is inexpensive, holds a good edge, is very sleek, and provides a level of quality that does not compare to anything else at a similar cost. You can likely purchase it from the camping/ gun section of your Wal-Mart.
Being in possession of the means to defend your right to live and to do so nobly, is something that you should always be in possession of.
