trovel
For cutting branches etc: Good bypass secateurs, snips, loppers and pruning saw
For digging: Spade, garden fork, square shovel. I always go for old tools with good handles, and give them a rub with linseed from time to time
(don't leave the linseed rag scrunched up-it has a habit of spontaneously combusting...)
My own place is very small and moving stuff around is easy.
in a 'job' situation, I carry my handtools in a sports bag and the big tools go in a wheelbarrow.
One of my handiest and low-tech 'tools' is bamboo. Stakes, poles, markers, hole-poker for legume seeds...
