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.

This is Estwing's newest geological tool and sure to become the standard the rock pick carried by geologist and rockhounds.
The main differences between the hammer (Big Face) and the Estwing Supreme 22oz Pointed Tip Rock Hammer is the new Big Face has, wait for it, a bigger face. Think of it like a bull dog or a pug. It's like the 22oz hammer's striking edge is "pushed in" towards the shaft. Like a mountain range created when two plates collide! Or like that day you spent hours pounding away on a chisel. The 22oz hammer's head is about 7/8'' square while the Big Face hammer's head is 1 1/8'' square, about a 1/4'' bigger on each side. Speaking of chisels, this rock hammer's head makes it much better for driving chisels.
Overall the weight of the Estwing Supreme Big Face 24 oz Pointed Tip Rock Hammer E6-24PC and the Estwing Supreme 22oz Pointed Tip Rock Hammer E3-22P are about the same. The Big Face has extra head weight which imparts a more powerful impact, but the overall weight was held the same by attaching the grip to the handle shaft in a different way. (see the images below)
Light enough to easily carry but heavy enough to crack some rock. Estwing Supreme quality in a one-piece forged pointed tip rock pick. Fully polished solid steel with the Estwing shock absorbing nylon-vinyl grip which has been tested to reduce shock by 50%.

The BelOMO 10x21mm(.85") triplet loupe magnifier has a viewing area of 0.65 inch (17mm), much larger than the Bausch & Lomb Hastings Triplet Magnifier. The 3 elements making up this achromatic triplet provide a bright and clear view. The 10x power magnification provides the best magnification to depth of field ratio and is the most popular power for a hand held magnifier. The housing and cover are machined metal and coated with a matte black finish and assembled using flathead screws. Belorussian Optical and Mechanical Association (BelOMA), makers of sights for guided weaponry, camera lenses, and other optical components manufacturers these loupes.
We highly recommend this loupe. This is the lens we use all the time.
Each BelOMO loupe we ship is custom treated to prevent the screws from coming loose with usage.
