This is almost the same rock Hammer as the Estwing Supreme 22 oz Pointed Tip Rock Hammer E3-22P. The difference is the use of a leather handle rather than the vinyl handle. The leather grip is made of laminated leather "O" rings pressed then riveted to the shaft. The whole handle is then laminated. The leather grip makes this hammer aesthetically pleasing as well as a great field tool. The leather is factory coated with a varnish that wears off with use.

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.
