These hammers are not used! They are all perfectly good, brand new hammers that have never struck a rock. They have just seen a little rough treatment along the way.
Sold ''as is''. You may return the hammer, at your cost, for a refund if it is returned in the same condition as when it was sent to you.
The colors, shapes and properties of minerals vary from the bland to the magnificent. Guide to Minerals, Rocks and Fossils is a practical and authoritative handbook that is both comprehensive and easy to use.
Each of the 600 specimens is shown in full color, sometimes in two or more forms. There are also drawings that show the structure of the crystalline specimens. It covers the basics like granite, as well as oddities like meteorites and tektites.
Fossils include sponges, corals, arthropods, brachiopods, and fossil land plants.
Each is described in detail, with notes on: - color and transparency - grain size - hardness - structure - occurrence - mineralogy - distinguishing features - habit - cleavage - texture - alteration - luster
Mineral names, chemical formulae and structural data accord to international standards. This is a very complete, but attractive and useful volume in a respected series.
Amateur Geologist note: This book originally was published by Cambridge under the title of Cambridge Guide to Minerals, Rocks and Fossils with this description: Whether hiking along a mountain trail, setting up camp in the field, or working in a garden, this is the definitive resource for anyone interested in identifying the rocks, minerals, or fossils they come across. Easily portable and with nearly 250 illustrations, with 145 in full-color, Cambridge Guide to Minerals, Rocks and Fossils is an indispensable handbook for amateur collectors and specialists alike. For each mineral, the authors explain and list the physical and optical properties, from crystal systems, hardness and fracture to color, transparency, and luster. They also discuss the occurrence of each mineral, as well as handy tips on their distinguishing features. For each type of rock, the Guide lists the color, color index, grain size, texture, structure, mineralogy, and field relations. In addition, for each fossil, the authors provide their corresponding type, age, and geographical distributions, along with detailed descriptions of their sizes and shapes. The clear, informative illustrations help elucidate technical concepts that often befuddle amateur collectors.
The Mineral Hardness Ruler is a stimulating visual aid, educates in one phase of mineralogy, and provides the standard ruler measurement scales needed in classes.
Rockhounds, mineral enthusiasts, students, teachers, geologists, and any one interested in rocks and minerals will find the Mineral Hardness Ruler a handy visual aid for quick information on mineral hardness.
The two-sided, flexible, glossy, vinyl ruler consists of five scales: three measurement scales and two mineral hardness scales. The measurement scales are in standard ruler measurements of tenths of inches, sixteenths of inches, and millimeters. Mohs' relative hardness numbers are integrated into the inch scales, while a separate scale exists for an absolute mineral hardness scale by Rosiwal.
On one side of the ruler are pictures of the ten common minerals, in full color, selected by Mohs for his relative hardness scale. On the reverse side of the ruler are six common items with their relative hardnesses. These items, along with known minerals, can be used as a handy field kit to test the relative hardness of an unknown mineral.
Hardness is one property of a mineral that can be used to distinguish among similar minerals. A given mineral can scratch any other mineral of the same or softer hardness. Over a hundred years ago, the German mineralogist Frederick Mohs devised the relative hardness scale that has found favor with mineralogists for over a century. Others, such as Rosiwal, formed absolute hardness scales using the same minerals as Mohs. For example, diamond, the hardest substance in Nature is not twice as hard as apatite, 10 versus 5, but over twenty thousand times as hard, 140,000 versus 6.5.
Estwing's Cushion Grip drilling chisel. Foam cushion grip to reduce impact. Heavy duty wide Hard Cap minimizes chips from flying off the chisel head and provides a wider head to help protect the hands from missed blows. Even has a centering target! This Estwing rock chisel has a bull or pointed edge. The tip is square, 4 sided, with each side tapering to a point. The bull point chisel for drilling into rock. Use it to gain accuracy when trying to remove specimens from the country rock. Maximum design hammer head weight: 3 lbs.
Due to limited product on hand: Limit One (1) per customer.
Estwing has replaced the leather sheath with nylon sheaths manufactured with the same basic design.
Estwing Leather Sheath for Pointed Tip Rock Hammers
New model. The sheath now has a "relaxed fit" making it easier to use in the field as well as working with more hammers.
Fits Estwing Pointed Tip Rock Hammers. Now fits the Estwing Supreme 24oz Big Face Pointed Tip Rock Hammer and the Valley Soft-Touch 20oz Pointed Tip Rock Hammer.
Leather snap case for the Estwing 24 oz, 22 oz, 13 oz, and 14 oz Rock Picks. Difficult to use until well broken in. We recommend the Gfeller Casemakers sheaths and holsters, especially the holsters. The Gfeller sheaths are sized better and their also pre-shaped to fit the hammers.
(I placed this on the site when the sheathshad a tight fit. It's still handy information." Hint: to make it easier to use this sheath use products like Vaseline, mink oil, saddle soap and even soap to help break it in. If you've recently broken in a baseball glove you may have some Rawlings Glovolium and Easton Glove oil around. Don't over do it. Do a web search on breaking in a baseball glove to find out how they do it.
I still don't recommend using the Estwing Leather Sheaths in any case. I sell them because some customers insist on having a sheath to protect things from the hammers. They're OK for storage but Amateur Geologist never carries one into the field. Use a holster.
Did I mention that these sheaths are just too difficult to use.
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.
