4 Prong Harrow
I gasped when I saw this tool. Imagine the possibilities to harrow tight, little rows by hand. I love sowing seeds directly in the garden. I practice many methods of interplanting, succession planting, and permaculture. That being said, sometimes you just want to create a little farm.
There is something so satisfying though about having tight, little rows. The idea of a garden, and food growing as a miniature farm has been firmly planted in our heads.
This harrow will create order and uniformity in your garden. I love using this for carrots, beets, celery, corn, and lettuce. Plants that can be tightly planted together and don't need to spread apart too much.
Remember to place seeds about as far apart as they will grow, and only 2-3 little seeds per section so you don't have to spend all your time thining, which damages the other plants.
Clearly made of rebar, this upcycled tool can also give you false bragging rights, as you suggest to people that you made it in your homemade blacksmith studio. I would tell that to kids at least and work your way up to see who believes you.
One way or the other, this tool will make you look like the biggest badass on the block and will come in handy should there be a Viking invasion or zombie apocalypse.
