Typically with gear such as knives, guns, flashlights, rods, reels, etc. I buy one use it if I like it I go back and buy another one or two if I can afford but always another one. I do this for several reasons, first we only have on child a little boy so one is for me and one is for him when he gets older, if I can afford a third its a spare in case one is lost, stolen, or damaged in some way that renders it unusable. Second, is given my luck the manufacturer will surely either discontinued that model, try and improve it and change it up which inevitable worsens it, or go out of business altogether. Third, I believe were in the midst of severe recession and in all probability or heading for a depression so I may not be able to afford all of this stuff in the future, or companies will go under and the items will simply be unavailable, etc. Fourth, if the first one breaks I have another one, if that one breaks I can probably cannibalize them both for parts and make a perfect working one, and still have parts for additional future repairs. I could go on but I operate off of two (2) philosophies, those being Two (2) is one (1) and one (1) is none, and the other is Better to have it and not need it, than to need to it and not have it.
