The “Guerilu”
The "Guerilu" is an ecolological digging fork. It can dig the soil without turning it over, thus respecting microbiotic life.
It is a useful tool for digging the soil without turning it over. It is in the same line of thinking as the “Biogrif”, the “Biofork” and he famous “Grelinette”.
It differs from these as it is made of galvanized steel, making it longer lasting, as the other tools often have wooden handles.
It is the brainchild of a gardening physiotherapist and a blacksmith. Their mutual experiments gave birth to the “Guerilu”, which is a solid, high performance tool, with a perfect ergonomic usage which allows you to dig without damaging your back. There is a large space between the handles for the body to pass through, which means you don’t have to bend your back when digging.
Like its rivals, it is very easy to use. You can dig deep, ventilate and break up the soil without much effort, and with minimal disturbance of the microbic life of the soil.
The tool is basically a fork with five teeth 20 to 25cms. long and has two handles a metre long which allow you to work the soil with a minimum of effort, using the lever principle.
Digging is done by moving backwards, keeping your back straight. The gardener drives the teeth vertically into the soil, holding the tool at arms length. He then brings the tool back towards himself until the handles pass behind his body. Backache is thus avoided as there is no need to bend over or to move backwards while digging. The soil is lifted and ventilated without being turned. The fork alternates between the longer and the shorter teeth which allows the right-to-left shifting movement to break up the soil perfectly.
The ergonomic use of the tool is produced by the angle of the teeth. When the tool is held with arms stretched, this angle allows us to drive the teeth into the soil perfectly straight. When the operation is finished, you simply move backwards to continue the digging. The width of digging is around 55cms. The tool weighs 5 kgs..
