The Estwing Supreme 16oz Chisel Edge Rock Hammer (E3-16BLC) is a smaller, lighter version of the Estwing Supreme 20oz Chisel Edge Rock Hammer (E3-20PC). This rock hammer has a 16 oz head and a a slightly shorter handle. This is a great rock pick for when you have a long way to carry the rock hammer, for those that prefer a lighter rock hammer, or those other times when you want a smaller rock hammer. Lighter to pack or wear on longer hikes. Choose a chisel edge rock hammer when you want to split layers of rock apart looking for fossils. The lighter weight gives a bit more control on where you place your strikes.
We've said it before but the purpose of a rock hammer is to break rock or drive chisels. With the lighter weight of the head of this hammer you're going to have to swing a lot harder and with many more blows. The smaller head face makes it harder to use when driving chisels.

The Valley Rock 20 oz Pointed Tip Hammer is similar in weight, and quality, to the Estwing 22oz Pointed Tip Rock Hammer. It is a smaller rock hammer than all the Estwing Rock Hammers except the Estwing 14 oz Pointed Tip Rock Hammer.. One piece drop forged design creates a virtually unbreakable heavy duty hammer - drop forged, heat treated, fully polished. The two-tone Soft-Touch Rubber cushioned grip is form fitting, shock absorbent and non-slip.rubber grip is finger fitted, shock absorbent and non-slip.
The Valley 20 oz Pointed Tip Rock Hammer is similar in weight, and quality, to the Estwing 22oz Pointed Tip Rock Hammer. It is a smaller rock pick than all the Estwing rock picks except the Estwing 14 oz Pointed Tip Rock Hammer. It has a square faced striking surface, larger than the Estwing rock picks, on one end and a pointed pick tip on the other. Made in China but it's high quality. We've sold over 2100 and have only had one returned for a broken tip. (The hammer had what looked like vice marks on it so I suspect the damage was artificially introduced.). This Valley 20 oz Pointed Tip Rock Hammer is a great tool for the professional, student, or recreational geologist and a great rock hammer for rockhounds. It will last you a life time.
