The oscillating (stirrup) hoe is a very efficient weeding tool that works both ways (push and pull). It does not disrupt the soil.
It is the perfect gift for a keen gardener.
Thanks for selling these by the way. I had a go with one on my little allotment in Kilkenny in Autumn and got loads of weeding done with it in a very short space of time. THe productivity gain was an eye-opener!
