Every home needs a tool kit, but what to buy first? It is hard to imagine how one would get along without these tools:
Buy the fancy one with several different tips stored in the handle. Make sure the handle is large enough to get a good, comfortable grip.
A pair of quality adjustable pliers is a a must. Buy a couple of sizes of Channel-lock type pliers. A pair of needle-nosed Vise-grips is invaluable.
Buy a quality claw hammer. 12 ounces is a good starter size.
By all means, buy several flashlights, but keep a small one in your toolbox. Throw some extra batteries in there, too.
It is tempting to throw your tools in the junk drawer in the kitchen, but have you looked in there lately? There is stuff in there that you thought you lost long ago. Buy a small tool box and keep your tools in it. You will always know where they are.
Once you discover the tool department at your DIY store, expect to become addicted. Each time you enter, you will see the neatest thing that you just can't live without. The clerk in the tool department is a good person to know. He (she) can recommend the right tool for the job.
