They eliminate the need for herbicides. Rough rubber hose is available for garden tool handles to give a better grip. Pruning shears - Felco brand recommended. They are much heavier but nicely designed so you can get down to the centre of the bush and do some good pruning. The blade comes off for sharpening.
Lighter shears are too flimsy.
Again, you definately get what you pay for with these tools. Watering cans - Hose watering cans give a nice gentle shower, really the best way to go rather than the round heads.
