Review: Best hammer for the price! - Very nice hammer, highly recommended, long lasting
Review: Industrial‑Strength Hammer Built to Last! - I recently added the Estwing Sure‑Strike Engineer’s Hammer (64 oz) to my toolkit, and it’s quickly become the go‑to for heavy‑duty jobs. The fully forged steel head is hardened and tempered for rugged work, and the yellow fiberglass handle with non‑slip cushion grip keeps it feeling solid in hand—even during extended use. 🏗️ Why It Rocks: Powerful Strikes: With a hefty 64 oz head and 14″ length, it delivers force that easily handles chiseling, fence‑post driving, wedge splitting—and even demolition. Comfort Meets Control: Balanced weight and a cushy grip make it feel lighter than expected—confirmed by reviewers who say, “for its weight it feels light”. Built for Durability: The fiberglass handle resists cracking under stress, and Estwing’s one‑piece forged tools are known for lasting decades. 💡 Pro‑Tips: Perfect for wedge splitting or driving stakes. Although the head’s substantial, the grip keeps arm fatigue at bay for longer work sessions. Verdict: This hammer hits like a sledge but handles like a precision tool. If you're doing structural, landscaping, or demolition work and need both durability and control, the Estwing 64 oz is tough to beat. A true five‑star workhorse.

## Questions & Answers

**Q: How long is the handle?**
A: 12”

**Q: Made in usa? or is that only the metal handle ones?**
A: Hi Brandon, 

It has a fiber reinforced handle with a good quality rubberized plastic coating. 

I'm sure that is only in the USA market, because I'm living in Europe, and I wasn't found anywhere else just in the USA available pieces.

Regards,

Otto

**Q: If it's a 64oz hammer how can the item weight be 2.45lbs. it seems that 64 divided by 16 = 4 pounds. wtf? unless the "new" pound is not 16 ounces?**
A: I agree with the review of 64oz = 2.45 lbs.  What math is that?  That review was from 2020 and here it is 2023 and it is still listed the same way.  I don't think the math has changed since 2020.

**Q: Is the blue grip on the handle rubber or plastic like the rest of the handle, I cant really tell?**
A: It is of a rubber compound of some sort.  I does cushion your grip some but it doesn't take the total shock out of the handle when you strike something. It is nice that the handle is epoxied into the head so it doesn't loosen up over time.

I use this to primarily to drive stakes in the ground- and to split wood - like the length of the handle, grip is good-
