Is the Corona 13-Inch RazorTOOTH Pruning Saw Worth It? One-Hand Cuts Up to 7 Inches

Who this saw is for

A branch too thick for anvil pruners but still small enough to cut with one hand is squarely what the Corona RS 7120 is built for. The 13-inch RazorTOOTH blade is curved and designed for single-hand use, rated by Corona to cut limbs up to about 7 inches in diameter, which covers most of the pruning a homeowner does above the lopper range.

This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.

What you get

The RS 7120 is a fixed-blade, curved pruning saw with Corona’s RazorTOOTH tooth pattern: three-sided razor teeth set to remove more material on each stroke than a standard saw tooth. The handle is an ergonomic pistol grip meant for one-handed control while the other hand steadies the branch. The listing does not mention a sheath or a folding mechanism, so this is carried and stored as an open fixed blade, not folded away like a pocket saw.

Blade and steel

Corona builds the blade from high-carbon Japanese SK5 steel, a tool steel known for holding an edge under repeated impact, and plates it in chrome to cut friction in the cut and resist corrosion. The teeth are impulse hardened, a heat-treatment step Corona uses across its RazorTOOTH line to extend tooth life under the repeated side loading that curved pruning saws see. Combined with the 3-sided razor tooth geometry, the blade is designed to bite fast on the pull stroke, which is where RazorTOOTH saws typically outperform straight-tooth hand saws.

Handle and grip

The pistol grip handle is shaped for a single hand squeezing through long strokes, with the curve of the blade putting the cutting edge in line with a natural pulling motion rather than a push. That curved geometry is why Corona rates it for single-hand use where a straight blade usually needs two hands to keep the cut tracking. It is not an ergonomic gel grip like Corona’s ComfortGEL tools, so expect a firmer, more basic feel in the hand.

Living with it

Owners of curved RazorTOOTH saws commonly note that the aggressive tooth pattern clears green wood fast but can grab and chatter in dry, seasoned wood, so letting the saw do the work on the pull stroke rather than forcing it keeps the cut clean. Wipe the chrome blade dry after use in humid conditions, since chrome plating resists but does not eliminate rust at the exposed cutting edge. Corona does not list a specific warranty term in this listing, so check the current product page before buying if coverage matters.

Alternatives to Consider

The Fiskars Power Tooth folding saw line covers a similar cutting range and folds flat, trading some cutting aggression for easier storage. For branches well past 7 inches, a bow saw or a cordless chainsaw with a small bar is the faster tool. For precision cuts under an inch, a bypass hand pruner is still the better choice than any saw.

Verdict

Buy the Corona RS 7120 if most cuts land between 2 and 7 inches and a fast, single-hand curved saw suits how the pruning gets done. Skip it if storage space is tight and a folding saw is needed, or if most work is on branches thicker than the saw’s rated range.
