Does Wal-Mart sell relatively good quality knives? - does wal-mart sell nutramax dogfood

I want to buy a knife for protection and for use at work (cutting into cardboard boxes and materials), and the only place where they can find in my neighborhood who sell knives to anyone under the age of 18 Wal-Mart. The knives are acceptable, or I should try a knife take off?
I am looking for something very high quality and expensive. Just something to cut red tape and cardboard, and gives me a bit safer start than I in the evening.
