There are wants, then there are NEEDS. I believe that I need these knives. For what you ask? Well, let me ask you this. Do you want to be in the middle of a zombie apocalypse and not have these knives? I feel like these are an eventual must. an eventual need. I told my wife that I need these, and that I'd like her to purchase these for me. She told me 'no, you are crazy' and after I stated my argument she told me that she 'likes to live on the edge'. So do I, but I think not having these knives is jumping off the edge.
