This set contains many useful things for your geological research. I'm just an amateur so I don't hit the rocks every day. But for me this kit was perfect and there's no reason it won't last long. Haven't used a chisel yet but have used a hammer to collect some samples of local conditions. The canvas bag is large and holds a lot. And just today, while browsing through part of the collection, I pulled out an LED-lit magnifying glass (I forgot it was in the set and "discovered" it at the bottom of a canvas bag). The optics are crystal clear and the LEDs are bright. I think I even managed to identify some of the stones. I live in a place where lava once flowed!
