Garden Glory Spade OnyxThe diamond spade, also known as trowel isnt just beautiful; its functional as well, with a handle that comes in a range of colors. And after youve used it, just leave it in the pot like a piece of jewellery. The diamond spades have blades in solid brass. For handles, we have chosen compression molded plastic simply because it is more durable than wood, and warmer to touch than steel.
