How to use a rock hammer or a rock pick?
Rock hammers are used mostly to crack open or split rocks. They can be used to fracture a specimen to reveal its crystalline structure. This is useful in geology for rock and mineral identification. In addition, rock hammers can be used to make rock specimens more appealing by revealing part of its structure.
Rock hammers can further be used to pry or split apart layers of soft rocks and sediments. They are often used by paleontologists and for amateur fossil hunting. Rock hammers are also useful in the field for clearing up small rubbles and to dig out hard to reach rock specimens.
Rock hammers are also used to hit directly a rock specimen. The shape of the head hammer directly affects the strength of the impact. For example, a pointed-tip will provide more power by targeting a narrower surface on the rock. In addition, the length and weight of the rock hammer influence the strength of the impact.
Beginner’s guide for finding the best rock hammer or rock pick
There are many types of rock hammers available on the market and it can be quite confusing for amateur geologists to find the best one for them. In fact, there are many things to consider when buying a rock hammer. The intended use in one crucial factor to evaluate, as some rock hammers are designed specifically for a certain type of rocks.
In addition, you need to think about the type of rockhouding that you intend to do. Indeed, you might want to think twice about the rock hammer weight or size when you expect to travel long distances on foot to access a site. On the other hand, you may want to bring a heavier rock hammer if you expect to encounter bigger or hard rocks.
It is crucial for rock hammers to be made from high-quality materials, due to the intensive work that they accomplish. Typically, a good rock hammer is made out of a single piece of hardened steel. The grip is generally made of rubber or leather. Both options can be good, but you should again keep in mind that their quality will definitely impact the comfort of the grip. In addition, high quality rock hammers are well balanced, which can further improve their use. Altogether, the overall quality/price ratio is an important thing to consider when buying a rock hammer. It might still be worth spending a few extra dollars to find a high-quality product with a good durability.

What are the different types of rock hammers and other geological tools?
There is a variety of rock hammers and other useful geologist tools available out there. The main categories include:
–Pointed-tip rock pick
–Chisel-edge rock hammer
–Crack hammer
–Pry bar
–Geological pick
Let’s now see in detail these different type of rock hammers, how to use these geologist’s tools and the best buying options available for each category.
Best rock hammer or rock pick
Most of the rock hammers or rock picks have a length that ranges between 11 and 13 inches (28-33 cm). Typically, a 16 oz hammer (450 g) is considered sufficient for most rock types, although metamorphic or igneous rocks can require more strength. There are also small hammers available. These rock hammers that weight 8 oz (225g) or less are perfectly suitable for children.
The head of the rock hammer is composed of two edges. The main edge is a square head with a flat surface used to hit rocks and crack them open. The other side defines if it should be considered more of a rock hammer or a rock pick. Generally speaking, rock hammers refer mostly to chisel-edge rock hammers. On the other hand, pointed-tip rock hammers are often referred to as rock picks. Let’s now see the differences between these two closely related rock hammers.
Pointed-tip rock hammer (also called rock pick)
The pointed-tip rock hammer is generally used for hard rocks. Rock picks are good for metamorphic, igneous as well as hard sedimentary rocks. The pointed-tip will concentrate the hit on a smaller surface, therefore increasing its strength. Therefore, pointed-tip rock hammers can be used to crack open or split a small specimen to reveal its composition.
Here are some of the best rock picks:
Efficere 22 oz pointed tip rock hammer
This rock pick is Amazon’s choice for rock hammers and has a score of 4.6/5 with over 1000 ratings.
This rock pick is a drop forged single piece of steel. It has a polished finish with an additional rust proof coating for maximal durability. The handle of the rock pick is made of rubber and offers a good grip. This pick is also well balanced. Overall, this rock pick has a good quality/price ratio.

Despite the very good ratings, some reviews pointed out that the rubber sleeve was glued to the metal and that it can break apart over time. Other reviews also noted metal deformations and dents when using it with hard rocks such as granite and basalt.
Nonetheless, this rock pick is still an amazing option for less than 25$. This is a very good rock pick for beginners. More advanced geologists may still prefer to invest a little more for better overall quality.
Estwing 22 oz rock hammer (E3-22P Estwing hammer)
The Estwing pointed-tip rock hammer has an outstanding score of 4.8/5 with over 1300 ratings. No wonder why Estwing is synonym of quality for most professional and experimented geologists.

Surprisingly, the following warning is engraved on the hammer head: “Pick head for prying only”. I am a bit confused by this label since it would defeat the whole purpose of having a rock pick. However, there are numerous reviews from satisfied customers that successfully used it for rockhounding.
Chisel-edge rock hammer (also called bricklayer’s hammer or mason’s hammer)
The chisel-edge rock hammer is generally used for soft rocks such as sedimentary rocks. The chisel-edge hammer is used mostly to pry or split apart layers of sediments. This is why paleontologists often use chisel-edge rock hammers to split slate or shale to reveal fossils. This type of rock hammer can also be useful on the field for clearing up loose materials.

Crack Hammer (also called drilling hammer, engineer’s hammer or sledge hammer)
The crack hammer is an essential tool for rockhounding. As its name suggests, this hammer is the perfect tool to crack rocks. The crack hammer has the weigh and power required to crack hard rocks. For example, crack hammers are useful to crack igneous rocks such as pegmatite vugs to reveal amethysts.
In addition, these sledge hammers can also be used in combination with chisel or a pry bar to crack or pry open rocks. Let’s now see some really good crack hammers.

Safety equipment for rockhounding
It is important to wear safety equipment while rockhounding. This includes good eye protection by wearing safety googles. Indeed, cracking rocks can cause sharp fragments to be projected at high velocity. Gloves are also essential on the field. It might also be a good idea to wear a hard hat on sites where rocks could easily fall or roll over.
Geologist’s pro tip
Just a quick tip when taking pictures in the field. It is always a good idea to include your rock hammer or rock pick in the picture. Since it has a standard format, it can be used as a scale to give an idea of the size of a geological formation or a rock specimen.
Conclusion
