I go to the dollar store and buy cheap bread knives, they work well and, for me, are easier to control around things like agapanthus roots. For digging in the garden I use a reciprocating saw to get through all the Live Oak roots.
Elaine, you are lucky, we have to blow the driveway and walks twice a day usually. Between oak leaves, acorns, crape myrtle leaves and seeds and pine straw, it is a mess here. We are taking the CMs out this year which should help but they are so large we need commercial tree guys to do it.
