I'm not sure if you can call them a "tool" or not, but I love these colored plastic buckets/baskets/bins
https://www.amazon.com/dp/B000A63M1I/ .
I have several of them. I use them when I am doing cleanup to hold the weeds, spent flowers, and prunings; the bucket is light and easy enough when full (so long as there is little or no dirt) to then carry out to the yard waste recycle bin. (No, I don't have a compost heap... I do not have a good place for one, really.)
I sometimes use the buckets to haul a few 1 gal plants from the car back to the garden.
I also use them for recycling dirt from pots (where plants have died (or should be deleted), where seeds have failed to germinate...). Dig out the plant (stalks, roots), dump the dirt into the bucket, repeat with the next pot. When I get enough dirt in there, I maybe mix in some compost or fertilizer (or else do so on an individual pot-by-pot basis), and then I re-use the dirt - either for another potted plant, or else out in the garden.
Right now I am thinking of doing something different wrt a potting recipe for my daylily seedlings. One of the buckets may become a mixing bucket for that purpose (to mix certain amounts of planting mix, vermiculite, mulch, fertilizer, alfalfa, etc.).
I just love these buckets!
I have bought other variations on this theme... including pop-up, collapsible/expandable buckets, and these ones are imho far better (not to mention that the colors are far more fun - and the buckets can be color-coded for use, if necessary).
