The Estwing Leather Gripped 13 oz Light Weight Pointed Tip Rock Hammer is best described as an Estwing Leather Gripped 22 oz Pointed Tip Rock Hammer (E-30) that has been trimmed down to reduce weight. The rock pick is similar is overall size to the Estwing Leather Gripped 22 oz Pointed Tip Rock Hammer (E-30). The handle is narrower but the handle length and the the length of the head are basically the same. It differs in that the hammer head striking end is a slightly smaller size and length. The pick end is the same length but tapered to a sharper point. Note that the 13 oz specifies the head weight not the total hammer weight. The 14 oz pointed tip is actually the lightest pointed tip rock hammer we carry.

Inside the front cover, Robert Hutchinson writes:
It began innocently enough. While photographing the Painted Desert, Atkinson became intrigued with the brilliant colors in the petrified wood scattered on the ground. He brought home some polished rocks, photographed them under glare-free lighting, and was captivated. The photographs looked more like paintings of forgotten dreams than either rocks or photographs. Atkinson proceeded to photograph thousands of art-quality polished rocks, bought or borrowed from international dealers and collectors, and to refine his photographic techniques.
From these thousands of photographs, Atkinson has chosen for ?Within the Stone÷ seventy-two that have yielded the most striking, the most poetic, and the most ineffable images. Atkinson opens a vault beneath our feet, revealing to our astonished eyes the tumult of color, form, and desire hidden ?Within the Stone.÷ He invites us to enter the dreams of Gaia. Some of these are epiphanies so far removed from our mundane experience as to beggar ordinary language and analogy.
Seventy literary pieces were commissioned for this book from seven writers. Every one of the writers has conspicuous attainments in both scientific and artistic modes. Each writer was asked to free-associate with his or her ten assigned photographs as though they were high-level Rorschach patterns. The seven contributors are Diane Ackerman (poet and psychologist), Philip Ball ( Nature editor and dramatist), John Horgan (science writer and philosopher), Andrew Revkin ( New York Times reporter and Hollywood screenplay writer), Dorion Sagan (science writer and novelist), Tyler Volk (NASA biologist and architect), and David Zindell (science fiction novelist and mathematician).
In an appendix, mineralogy experts Si & Ann Frazier and Robert Hutchinson provide mineral commentary for each specimen.
In this book two renowned experts share their lifelong passion for geodes and their extensive knowledge of world-class geode deposits as they present the latest theories on the formation and occurrence of these amazing mineral gifts of nature.
The most comprehensive book ever written on geodes of the Americas - a definitive reference for serious collectors and a delightful mineral exploration for both experts and novices.
The famous Estwing Geo/Paleo Pick GP100 has made a grand reentry after being out of production for several years. The handle has been beefed up to make the unit even stronger. It is 25 inches long with a total weight of 3 pounds. Painted steel with a soft vinyl grip. The light weight but great strength of this makes it a great field tool for any geologist or rockhound.
Not only is this a great digging tool but I use mine to help me navigate the steep slopes of mine tailings. Jab the tip in and pull yourself up then use the hoe end to cut a quick shelf to work from.
The Deluxe Moh's Hardness Pick Set now comes in two case types. The wooden case is small enough to carry and the top screws into the base to make a perfect desk stand. The plastic case is longer but the thinner size makes it easier to carry in your field tool set.Hardness is an important and quantifiable physical characteristic of a mineral and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities. Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral.
Chisel edge rock hammers are typically used when you want to split layers of rock apart when looking for fossils.
