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.
