Size: 16-Ounce Curve Claw
In a way I feel weird reviewing a hammer, afterall it is a hammer! However, I thought I would put my 2 cents in, in case someone was looking to buy this.

I like the hammer, I have two claw hammers. This one and a wood hammer. This one seems a little top heavy to me. This may be do to a lighter fiberglass shaft, but I can easily compensate for it. The grip is comfortable and makes hammering without any workgloves effortless.

I have had this hammer about 5 years and I must say I am not disappointed in it at all. Would buy it again.

It's light weight; I crawled around on my back in a 2-3' high, 1300sq/f crawl space installing 6 lights (receptacles and all). Took about 2 hours and hammering those receptacles in with my arm crooked and barely enough room to get a decent swing was no problem. I actually had a harder time screwing the outlets and fixtures into the receptacles than banging the nails in. The floor joists were the old white oak too, dense and solid.

It's got good balance; light weight handle with a solid, heavy head make it real easy to get a good swing. The shaft is fiberglass but it has a rubber grip so even with sweaty hands it's not going anywhere. And I personally feel that fiberglass is a lot easier on the hands but a couple of old timers I work with still like wood better.

Seems pretty durable; We've been doing a lot of demo work with it for 2 weeks now and it's done everything from pounding nails to pounding pry-bars and chisels as well as knocking out old cripple studs. I've also been yanking old 3 inch nails out of concrete and brick.

It sounds silly but the color is actually kind of a plus as well, makes it a lot easier to spot when you leave it laying somewhere on the job site. We had a couple of dark red hammers as well and whenever one of us would need a hammer that's usually the first one we grabbed just because you couldn't miss it sitting there.

I think like I've given it a good run and a serious amount of abuse. I'm pretty happy with it.

Size: 20-Ounce Rip Claw
This hammer is a decent hammer there is nothing wrong with it. Have worked in construction for my whole life. If you want a durable hammer, that has no frills this will pretty much do the job.

I would choose a stanley fat max,Vaughn, or Estwing, but this is a very good homeowner hammer. Its handle is a little short so the leverage is not that high. However, that is personal preference.

Perhaps because it's fiberglass it has more "resonance" to its swing and subesquent impact. It fits the hand and is a pleasure to use.
And, it's a Stanley product.
Good tool! Good job Stanley!

Size: 20-Ounce Rip Claw
I love this hammer. When I am framing and need the weight behind it, this hammer does a great job. At 20oz. I can get enough power behind each swing to really drive the nails. As with most other Stanley hammers, they are built to last. Unless something catastrophic happens to the hammer, you'll be owning this one for many years.

While this is a great hammer, it might be too big for the average homeowner looking for a hammer for household jobs. Also, the flatter rip claw is made more for prying boards apart. Most homeowners will want the claw for pulling nails, and permanently marring up their walls; I would suggest the Stanley 16oz curve claw hammer.

This is a really nice little hammer. I'm not a huge fan of Stanley tools, but I like this one.

Of course, it's less than half the punch of a regular 16-oz hammer. But that's a plus for so many tasks. Also good for camping (tent stakes) when lighter/smaller is a plus.

Very nice rubber grip.

Actual dimensions are: 11.1" x 3.9" x 1.2"

Shop around. Mine is from Wal-Mart at under 6 buckss.

I must admit I have fondled many hammers during my time. Whenever I visit my favorite hardware haunts, I pass by the tool crib and pick up a dozen or so to find that hammer with just the right balance, grip and finish. This Stanley is the best I've found for a price not much greater than those with hard wood handles. The cushioned grip has a slight curve at the bottom that makes it feel very secure in the hand, and the balance I found remarkable. The finish on the head and claw is evenly ground with a protective finish that makes it look really good when you first get it, although it wears off with use. The yellow fiberglas shaft looks sharp and feels strong when you strike that 10 penny. A basic tool if ever there was one, but very well done and suitable for amateur and pro alike. Thanks, Stanley, and thanks Amazon!
