K So I own a few Decently Expensive items (Well Expensive for me and in my opinion) Such as say the Quark aa2 Tac light. Now this light was roughly 70-80$ and I personally consider that expensive for a light. Now I am considering to purchase a 14$ Light to use when I know for a fact the lights gonna get abused and may not pull through the ordeal.

Does anyone else do this? I have done it with knives shoes Multitools lists goes on. Is it sensible or is it wasteful?
