I broke my shovel at home last week digging out a smaller-growing bamboo, Semiarundinaria yashadake ‘Kimmei’. It was at least ten years old, the shovel that is, and I broke it the way most people do, prying with it. I’m not nearly as hard on shovels as I used to be; I know their limits, but I was tired of this shovel. It was one of those thin-gauge “stamped” shovels that hardware stores sell these days to consumers, inexpensive and cheaply made; the kind of tool a person could buy many times over the course of their gardening life. I have broken several in the past jumping on them, with two booted feet, while trying to cut through heavy soil and roots, or like I did here, levering to hard before the object of my attention was adequately cut free of its earthly ties. Stamped shovels flex due to their thinness. Any flexion causes an inefficient transfer of energy when attempting to drive the blade against resistance. Think wasted energy and more effort. Stamped shovels have a soft fold where the smooth curve of its bowl bends into the vee that becomes the sleeve that then wraps around the shovel handle. This shaping of the blade adds some rigidity that the same material flat doesn’t possess. Any such bend in a piece of metal, however, becomes the weak point. This is where the metal breaks. Finding a quality replacement requires special ordering or buying through someone who serves the nursery or landscape trades.
