This really has been my favourite over the last few months. It's not a sickle as we know it, more a hand hoe; use in a scythe like movement to deal with emergent weeds and angle down to deal with the bigger weeds. Great for getting in around and behind the tomato plants. All the time knowing the copper in the bronze is doing good for your plants and the soil and, at the same time, discouraging those annoying slugs and snails. It's with me all day, in my back pocket when not in use.
We're asked about this a lot and the answer is simple. Almost all bronze/copper gardening tools are made of bronze (an alloy of copper with a little bit of tin). Pure copper would be too soft. That said, our dibber is sheathed in copper but then it needs no strength. So whenever you read or hear about copper gardening tools, you can pretty much assume they are referring to bronze garden tools.
