Hand fork, trowel, secateurs, Japanese onion hoe, and a mini crowbar are the tools I use most. Have a border fork and spade too, but my soil is very light and free draining. The mini crowbar is great for levering clumps of crocosmia out of my dry stone walls, and weeding cobbles. But the most life- enhancing is a pair of Velcro strapped knee protectors. I always found kneeling pads a bit of a hassle. Mind you, the knee protectors are so comfy that it's easy to forget you're wearing them, and I have found myself downtown with them on. Whoops!
