Hmmm, interesting question. Depends.
For sowing seeds in the ground, I use a rake and a hoe, just use fingers to drop seeds. If just a few flower seeds, I get down on my knees instead. I got an official dibber as a gift, it must be for big vegetable seeds, seems too big for tiny flower seeds so I rarely use it. I like my Gardening Pants with knee pads built in, from Duluth Trading Co. Nice gift for the gardener. Gloves, the thin kind with nitrile coating so I can feel what I am doing.
Sowing in little pots or flats : workbench or table, big plastic bin thing (TubTrug) and big metal scoop to mix the dry bagged potting soil with water. Then use the scoop to put soil in pots. Fingers and little home-made dibber thing (whatever is handy like a pencil!) to make holes, trenches. I have a Brother P-Touch Labeler that is a kind of nice gadget (also use around the house, nice gift for gardener, homeowner, crafty person).
Planting bulbs. For a lot, I got a giant screw thing that you put on cordless power drill, it is designed for bulb planting but is $$$ and you have to have the drill. For just a few bulbs I do have one of those "bulb planter' hand held thingies, they works OK unless you have too many rocks in which case ordinary trowel is better. Also the bulb planter does not work in sand as it cannot pull up a "core" of soil, just use trowel.
Wintersowing is a bit more complicated. I use Kitchen scissors (designed to cut up chicken etc so very sturdy) and tinsnips to cut up milk jugs and gallon vinegar jugs. I use a soldering iron to quickly burn holes in the jugs to wire them closed and make drain holes, but you can punch holes it is just a pain in the neck to do a lot. Then planting is like the above in pots.
