Thanks for all the replies, i didn't explain myself very well. I seen somewhere , can't remember where, the coin relic hunters modify a garden spade as a digging tool
in softer ground. They shape the blade of the spade to a point and cut saw teeth down the sides for cutting grass roots.
I can go freehand but seeing one already made would make it simpler. I have all the long handled picks for gold prospecting but thought a spade would be better
for coin relic hunting.
kind regards minersright.
