How to Cut Metal Landscape Edging | Clean Cuts, Right Tools

Cut metal landscape edging by measuring, marking, clamping firmly, and using the right saw — tin snips for thin steel, an angle grinder or reciprocating saw for thicker material — then deburring every cut edge.

Here is the tool breakdown, the step order that actually works, and the finish that keeps your edging safe to handle.

The Right Tool for Your Edging Thickness

Thin edging — around 14 gauge or about 1/8 inch thick — can be cut with tin snips or metal shears. These are fast, quiet, and leave a clean edge when you cut in short, overlapping bites. For thicker steel edging, tin snips will bind and strain your hands; switch to an angle grinder with a metal-cutting disc, a reciprocating saw with a metal-cutting blade, or a hacksaw for short straight cuts. Hacksaws are slower but give you control and leave a straight edge when the blade is sharp and the edging is clamped tight.

For curves and custom shapes, use small overlapping snips instead of trying to make the cut in one pass. Tight curves may need a series of relief cuts — small notches snipped into the waste side — so the metal can bend without buckling.

Skip the measuring-and-guessing approach.

1. Measure and mark. Use a tape measure and a permanent marker. Double-check the length before you make a single cut — once the steel is shortened, you cannot add it back.
2. Clamp securely. Clamp the edging to a solid work surface or sawhorse. If the piece moves while you are cutting, the blade can bind, the cut will wander, and you risk injury. Two clamps are better than one.
3. Cut slowly along the line. Let the tool do the work. Forcing a hacksaw or grinder causes blade breakage and jagged edges. On thin edging with tin snips, take small bites. On thick edging with a power tool, keep a steady, moderate pace — do not push harder when the blade slows down.
4. Deburr the cut end. Run a metal file, sandpaper, or a grinder along the cut edge to remove burrs and sharp corners. This is the step most people skip, and it is the one that prevents stitches later.
5. Check for sharp spots. Run a gloved finger along the edge before installation. Any catch means another pass with the file.

Safety You Do Not Skip

Eye protection is non-negotiable — a chip of flying steel can end your day before the first piece is in the ground. Gloves keep cuts off your hands during handling. Ear protection matters with any power tool: an angle grinder at ear level is dangerously loud within seconds. Avoid cutting too fast; a rushed cut produces an edge that needs extra filing and risks the blade grabbing the metal.
