It has four metal prongs on the bottom which you position over the centre of the weed.
Then you use your foot to press the prongs into the ground.
Pulling back on the handle, which acts as a lever with the footrest as a fulcrum, causes the prongs to close over the weed and it comes out of the ground. This takes very little effort.
The weed is held in the prongs until you slide the yellow handle (half way down the shaft) down and it pushes the weed off the prongs. This is good if you want to put them in a barrow or bucket to dispose of.
No bending is required and the tool is lightweight. A winner all round...except if you are a weed.
Thank you to my daughter for giving this to me as a Christmas present last year. I love it!
