Buy Corona RazorTOOTH Arborist RS 7120 – 13-Inch Professional Pruning Saw

Description

The corona razortooth arborist pruning saw is a 13-inch professional saw for medium to large limbs.

When a limb gets too thick for secateurs, the saw you reach for decides whether the job ends with a clean cut or a torn stub. The Corona RazorTOOTH Arborist RS 7120 is built for that exact moment.

Its 13-inch curved blade is shaped to pull through green and dry wood alike, and the RazorTOOTH pattern clears material on every stroke instead of binding halfway through the cut. Arborists and serious home pruners choose a saw like this when the work moves above head height and the branches stop being twigs. This page covers what the RS 7120 is, how its blade is built, where it fits in a pruning kit, and what to check before you buy.

Key Features

• 13-inch curved blade. The curve keeps more teeth in contact with the wood through the stroke, which helps on thicker limbs where a straight blade tends to skate. The 13-inch length suits medium to large branches without turning the saw into a two-handed tool.
• RazorTOOTH three-sided teeth. Each tooth is ground on three sides, so it cuts on the pull stroke and clears the kerf as it goes. Corona describes this pattern as cutting up to twice as fast as a conventional hand saw.
• Japanese SK5 high-carbon steel. SK5 is a hard, edge-holding steel that suits a blade expected to stay sharp through a season of pruning. The trade-off with hard steel is brittleness if the blade is twisted in a cut, so straight, steady strokes matter.
• Cuts limbs up to 7 inches in diameter. That range covers most orchard, shade-tree, and large-shrub work that does not call for a chainsaw. Anything thicker belongs to powered equipment.
• Ergonomic grip for single-hand use. The handle is shaped for one-handed control, which matters when the other hand is steadying the branch or holding a ladder rail.

Product Description

The RS 7120 is a fixed-blade arborist saw, not a folding model. The blade is fixed to the handle, so there is no pivot to wear loose and no folding mechanism to jam with sap. That simplicity is a deliberate choice for professional use, where a saw gets pulled out dozens of times a day and must work the same way every time.

The blade’s curve is gentle rather than extreme, which keeps the cut controllable on smaller limbs while still giving the bite needed on 5 to 7 inch wood. A sheath is the usual companion for a fixed saw like this, and it is worth having one before the saw goes into a tool bag or onto a belt.

For buyers comparing fixed-blade options, the corona razortooth arborist pruning saw has no pivot to wear loose and no folding mechanism to jam with sap.

Benefits

A clean cut heals better than a torn one. The three-sided teeth leave a smooth surface on the branch collar, which is what the tree needs to seal the wound. Speed matters too. On a day with twenty limbs to remove, a blade that clears its own kerf saves real time and real arm strain. The fixed design also means nothing loosens over the season, and the SK5 edge holds up between sharpenings better than softer steel. For a home gardener with a few mature trees, that adds up to a saw that stays useful for years rather than one season.

That combination is why the corona razortooth arborist pruning saw is a practical long-term choice for gardeners with mature trees.

How to Use

Start the cut with short, light strokes to seat the blade, then lengthen the stroke once the kerf is established. Let the teeth do the work and keep pressure steady rather than forcing the blade. For a limb you are removing entirely, cut just outside the branch collar and do not leave a long stub. For a heavy limb, make an undercut first, then cut from the top a little further out, so the limb drops without tearing bark down the trunk. Wipe sap off the blade after use and dry it before storage.

After use, the corona razortooth arborist pruning saw should be wiped clean and dried before storage.

Why Choose This Saw

Choose the RS 7120 when your pruning regularly involves limbs thicker than 3 inches and you want a fixed blade that will not develop play at a pivot. It is the right pick for orchard trees, mature shrubs, and shade trees where a folding saw feels short. It is not the pick for pocket carry or trail work, where a folding saw wins on size. If your work is mostly twigs and small stems, a smaller saw will feel lighter and quicker.

For that work, the corona razortooth arborist pruning saw offers a fixed blade and a 13-inch curved edge.
