Details
Splitting a trunk to reduce its diameter or open a hollow is a controlled fracture, not a cut — and a tool that flexes under that load will wander off your line. The Edge Series trunk splitter is forged from manganese-infused stainless steel, dense enough to drive straight through hardwood without the jaw deforming.
Trunk splitting puts more stress on a tool than any other bonsai operation: you are wedging apart living wood, often against the grain, with your full body weight behind it. The added density of manganese-infused stainless holds the tip geometry through that, so the split follows the line you set rather than tearing sideways into tissue you meant to keep. Clean splits heal; torn ones scar for years.
Features
- Manganese-infused stainless steel for a denser, harder working edge
- Tip geometry holds under heavy wedging loads without deforming
- Machined and hand-balanced to the same spec as the rest of the Edge Series
- Corrosion-resistant stainless — no oiling routine required
- Priced in line with the Edge Series cutters at $55
Perfect For
- Trunk reduction and taper work on collected or field-grown material
- Opening hollows and shari on deadwood features
- Advanced growers doing heavy structural work
- Completing an Edge Series bench alongside the concave, knob, and root cutters
