Starting my Eurypterid collecting in 1994, work was done with a hammer and rock chisel.
In the early 2000's I was sawing to improve my chances of finding Eurypterids. (yes, I wear a particle mask if the dust is in my face.)
My next plan is to jackhammer the tough Bertie Dolostone.
Plan to try the new toys this next Friday, hoping the investment was worth it.
Ultimately the specimens still have to be sawed and chiseled out. The real trick is finding them first.
