Just love this thing. A tiny version of a tool I already love. Pencil for scale. This is not a standing use tool.
"Rub" it along the surface of the soil to cut off weeds. In SWFL conditions I recommend waiting until the soil is DRY and it will remain DRY for a day. Our weeds somehow manage to be cut off and send down roots from the cuttings. If using this, or the larger tool, in the summer: REMOVE THE WEED after cutting it off.
