The Wife is in the process of making us a boy...  Not so sure I want that but I guess my desires no longer matter.  She did however buy me a sword (LoTR), so that is really cool, lol.  She also allows me to purchase pretty much what I want in terms of knives and is, for the most part, ok with me purchasing guns.  We each have an allowance to use what we want it for.
I use knives for opening just about everything.  I use them to cut my nails and cuticles (often ending up a bit bloody to the annoyance of The Wife).  I use them to carve wood.  I recently used my hatchet to cut up our hurricane Ike blown down shed.  When (if) the SoD comes it will be used to clean up the back yard and for a camp knife.
I hope to be healthy enough to go camping sometime soon.  Although with The Wife's current, uh, condition, I doubt I will be able to go camping for a long time.
