Broadfork is a tool that was invented in France in the 1960’s (la grelinette in French). It’s very easy to use, although on heavier soils the heavier gardeners are going to have a bit of advantage. After only one usage of the broadfork, the soil is much lighter and easier to work with, but remains alive and undamaged. Keep it covered by either plants or mulch (or both), add liberal amounts of compost and you will have a beautiful rich fertile soil. In a few years the soil will become so dark and fluffy that you won’t even have to use the broadfork anymore.
Our broadfork is fairly light, weighing only 6 kilograms together with handles. Not that it really matters that much because if you use it properly you should not have to lift the broadfork at any point, but it’s much nicer to carry around a lighter tool. After careful research and testing we settled on this design which uses five laser cut metal tines made from flat steel, rather than thick round tines. It’s 65 cm wide so you can work a standard 75 cm garden bed in one pass. It’s very sturdy because of the choice of materials but also the design itself. The tines are protruding all the way through the shaft and are welded from both sides for additional strength and momentum.
