This really is a tough question. I tend to look at almost everything I own as a tool. I'll give some examples.
Hammers: I have many hammers. I have a couple of different weight framing hammers, a couple of finish hammers, different weight sledge hammers, different size and weight mallets for chisels, different ball peen hammers, rubber and copper and brass driving mallets. I don't use them all every day; but when I need a hammer, I use the right hammer.
Saws: I have three band saws for ripping and re-sawing and scroll work, a table saw, a track saw, many various hand saws, two jig saws, back-cut saws, chain saws, trimming saws, a couple of circular saws, and camping saws.
Drivers: I won't even try to list all the screw drivers, nut drivers, Torx drivers, and specialty drivers.
Firearms: Hunting, self defense, collectibles, recreational, target, and survival.
Bass guitars: 4 string P (rounds), 4 string jazz (rounds), 4 string PJ (flat wounds), 4 string Sterling MusicMan (we'll see what ends up on this one). I still would like to get a Uke bass and I need to attempt the 5 string world.
I am not a man of frivolous money. My wife and I are both public educators. However, I have learned the lesson that I am too poor to buy cheap tools that need replacing or boutique items that don't hold value. I tend to find a quality level that meets my finances and my particular needs. I also tend to think in terms of purchase price and resale ability. I will always shop for a good used item, but I won't hold off on not owning something I need. I rarely pay retail for anything except beer and petrol.
