Not necessarily tiny, but awesome single-purpose gardening tool for removing weeds without overworking your back.

Wirecutter did a write-up on a similar stirrup hoe that works "in half the time of pulling weeds by hand:" https://www.nytimes.com/wirecutter/reviews/garden-weeding-to...

Both have long handles for use while standing up, but grampa's weeder seems to target one weed at a time while the stirrup hoe is meant to cut several roots in one go.

So perhaps use grampa's to dig out dandelions from your lawn, but a stirrup hoe to get all the weeds between the plants you want to keep in a flower bed or garden.
