- Digging trenches
- Irrigation lines
- Drainage
Buy this only when you have a trench to dig: sprinkler lines, drain pipe, edging cable, French drains. The narrow 4-inch blade leaves clean vertical walls and removes far less spoil than digging a trench with a regular shovel.
Pros
- Narrow 4 in blade cuts tidy trenches for irrigation, drainage or low-voltage wire
- Long shaft plus deep blade clears a trench with far fewer passes than a spade
- Heavy 14-gauge USA steel and fiberglass handle hold up to repeated prying
Cons
- Single-purpose tool: useless for scooping piles or digging wide planting holes
- The deep narrow blade is heavy and unwieldy for anything but trench work
- Priced above a basic drain spade because of the made-in-USA steel
