I'll start off as usual Gil then when I go wrong you can jump in ( as usual )
Chris, There are a large number of digging tools and they suit the very different ways different people like to dig. You really should should visit some pay digs and see them in use.
Some people like Gil & I and many others count tools as all part of the hobby and are hand made.
Look at the new postings, I just brought up an old posting in reference to tools. " WIGGLE PICK PICS "
There are a lot more pics and how toos in old postings..
