These tools are a real innovation in traditional digging tools.
The large, comfortable circular handles allow a greater range of natural hand positions, avoiding wrist strain. The steps on the spade are larger, higher set and offset slightly from the shaft, to provide a wider surface with better foot registration than traditional steps. The steps are also folded forward and slightly curved (traditional steps fold backward, toward the user, and are straight), which softens the corner to reduce ankle injuries. Last, the angle of the step is slightly greater than the traditional 90° relative to the blade, providing a better push angle.
The transplant spade and border fork are for lighter work such as digging borders, transplanting perennials and working in close quarters. The spade is 42" long, has an 11" × 6 1/4" head and weighs 4 lb 4 oz; the fork is 41" long, has a 9 1/4" × 5 1/2" head and weighs 4 lb.
Both tools have a resin-encased steel shaft core and a stainless-steel head. They are so strong that you can apply over 150 lb of prying force at the end of the handle without breaking it.
They are also sold individually.
