  • Mineral Hardness Scale Ruler

    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.

  • Lanyard, Plain Black, 3/4in Nylon, with Quick Release Buckle and Split Ring

    Lanyard, Plain Black, 3/4in Nylon, with Quick Release Buckle and Split Ring

    Heavy duty 3/4'' plain black nylon loupe lanyard with a quick release buckle and a split ring. This lanyard may be used for any purpose but we've had it custom manufactured specifically for use with the BelOMO loupe.

    Important: We offer this lanyard for no additional charge when you buy the combo package of the BelOMO loupe with attached lanyard. Attaching the lanyard requires a screw to be removed so let us do it. We've been doing it for years and you save money!

    Use the split ring on loupes with a mounting hook. To use the lanyard with a BelOMO loupe remove one screw on the support shaft of your BelOMO loupe, swivel the frame out of the way and slide the end over the support shaft then install the screw again. Don't use the split ring to attach the lanyard to the loupe. (We suggest that you purchase the loupe with the lanyard already installed.)

  • Estwing Leather Sheath for Pointed Tip Rock Hammers #3

    Due to limited product on hand: Limit One (1) per customer.

    Due to increasing cost of leather it is no longer cost effective to manufacture the leather sheaths.

    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.
