Excellent and hard-to-find tool. I didn't even know it existed, I discovered it from a video on YouTube. For the handle, I used a long one, shorter than an axe and longer than a scythe. I use it intensively and exclusively for cleaning olive tree roots, from weeds, branches (small-large). The switch from cutting to digging has been very helpful because many branches are in the soil. It also helps with removing weeds, wrapping, and pulling. Very clean and precise work around the root, which I prefer over the bulky ones of a lawnmower. I'm thinking of getting a second one.
