I attach a pic of K&S oscillating hoe (OH) as requested by Still playing with tractors: the blade pivots back and forth to give a deep hoeing cut in both directions. I believe it would be better if the fixed angle of the head, relative to the handle, was a little slacker or the blade swiveled a bit more. Unfortunately there isn't enough of a gap to file down the pivot "stop bars" to increase the amount of swivel. It's awesome on the pull stroke though, even in consolidated soil. It can be equally awesome on the push stroke, but, as I said, only with a more upright body stance to get the forward blade edge at a good angle (= more effort). I'm using it to "weed" close up to young willow and apple stock: the design helps prevent stem damage. Just wondered whether anyone had found another brand/different design in the UK: there are many other OH designs, but UK options very limited from what I can tell. (I guess I shall just have to hoe more frequently to keep the soil loose - whereupon, the 170mm bladed option might be added to the inventory!)
