Taking a quick coffee break here at work, I'm looking at my Estwing 16oz straight claw hammer I bought almost 30yrs ago. It still does the job now, as it did when it was new. When I first got into carpentry work, I started with a home builder who did much of the work on his houses. He subbed out electrical, and HVAC work but we dod everything else. I quickly noticed each man on his crew carried an Estwing hammer, and many owned two, one for framing, and a lighter one for finish work. There's a reason for this. Estwings are tough, American made quality tools. They last a lifetime. I own four Estwing Tools now, a heavy framing hammer, the 16oz hammer, a 3lb small sledge hammer which belonged to my dad, and a leather handled campers hatchet. All are at least 25 yrs old, and all still get the job done every day. It would be very hard to find a product that's American made, that offers this much durability, for the price. If they start to rust, simply sand them off and and give them a light coat of oil. They'll be good to go for a lifetime. Just like Channel Lock pliers, one of the great American tool companies, still doing it right. I know there are many tradesmen, and retired trademen on this site. Do you still use or have you used Estwing tools. In my opinion,the best hammers on the market. You simply can't go wrong ??
