A single tine cultivator, the best tool for weeding or loosening soil in tight spaces between plants, is called a Finger Hoe. Our hoe has its question mark shaped head forged from low carbon steel. It's tough. We start with a half-inch round rod that is then shaped in the forge so the lozenge-shaped tip of the tine is a bit thicker, and longer lasting, than similar tools.
The Finger Hoe is useful for more than tillage. We know a nurseryman who uses them to maneuver one gallon plants around the enclosed bed of his pickup truck. It’s also a great tool to drag brush after a long day of pruning.
