I used to have a “garden hoe” and loved it. I loved it a little too much and its handle broke. I do not have the equipment to fix its handle.
Currently I am using a small, short mattock, which is good, and better at cutting through sod than the garden hoe (would have to tilt side to side to cut it effectively). I also have used a large mattock, which, while very effective, is heavy and exhausting to use. It would be very efficient for heavier, rockier soils. I use hoes not so much to weed growing beds, as to prepare the soil, build earthworks, etc. The garden hoe was perfect for that and made it so much easier.
I would like to get a warren hoe at some point, because it seems like it would be especially good for some of my uses (deep weeding).
Timothy—that one you have looks excellent for pond digging!
Another advantage of hoes over shovels for digging is that they can be used bare-footed without any special affixions. (See
