The famous Estwing Geo/Paleo Pick GP100 has made a grand reentry after being out of production for several years. The handle has been beefed up to make the unit even stronger. It is 25 inches long with a total weight of 3 pounds. Painted steel with a soft vinyl grip. The light weight but great strength of this makes it a great field tool for any geologist or rockhound.
Not only is this a great digging tool but I use mine to help me navigate the steep slopes of mine tailings. Jab the tip in and pull yourself up then use the hoe end to cut a quick shelf to work from.
