I couldn't get by around my home without these four additions:
(1) Solidly built LED flashlight - both low power (small sized) and higher power models
(2) A Dremel Tool with lots of extra bits - cutters, grinders, sanders, etc.
(3) A utility knife you aren't afraid to use hard - therefore no "trophy knives" - I use a $10 stainless Mora for this
(4) Paracord
