Quick verdict
A 10 inch curved blade folding saw that locks open for cutting and locks closed for safe carrying, built from high carbon steel and aimed equally at yard pruning and outdoor trail use. It suits anyone who needs a saw for branches too thick for a lopper but does not want a bulky fixed blade saw taking up pack space. The caveat is scope: at 10 inches this handles limbs, not trunks.
Strengths
- Curved blade keeps more teeth engaged per stroke for faster cuts
- Folding, lock-back design is safe to carry in a pack or tool belt
- High carbon steel construction for lasting sharpness
- Ergonomic non-slip handle grips well even wet or gloved
- Doubles as a camping and trail tool, not just a yard saw
Weaknesses
- 10 inch blade is not sized for thick trunks or large limbs
- Curved blades are harder to resharpen at home than straight blades
- Folding mechanisms add a pivot point that needs occasional cleaning
- High carbon steel needs drying and light oiling to avoid rust

Who this saw is for
Once a branch gets too thick for a lopper, the next tool in the kit is usually a saw, and the Corona RazorTOOTH 10-Inch Folding Pruning Saw is built to bridge yard work and outdoor trail use in one compact package. The curved high carbon steel blade folds and locks closed for safe carrying, which is why Corona markets it as much for camping and backpacking as for pruning around the yard.

What you get
The saw has a 10 inch curved steel blade in a folding body with a lock-back mechanism that locks the blade open for cutting and closed for storage, the same safety concept used on folding pocket knives scaled up for a pruning tool. The handle is described as ergonomic and non-slip, built to stay controllable in wet, muddy or gloved conditions. Corona positions the blade material as high carbon steel for long-lasting sharpness and toughness.
Curved blade cutting performance
A curved blade geometry keeps more teeth engaged with the wood on each stroke than a straight blade would, which is the main reason curved pruning saws generally cut faster through branches and limbs. Corona’s RazorTOOTH tooth pattern is designed specifically to grab on the pull stroke, which is standard practice for pruning saws since that is the stroke doing most of the cutting work when reaching up into a tree. The trade off of a curved blade is that it is more involved to resharpen evenly at home than a straight blade, so most owners either live with periodic replacement or send it out for sharpening once the edge dulls past a quick touch-up.
Folding design and portability
The lock-back folding mechanism is the detail that makes this saw as much a trail tool as a yard tool. Locked open, the blade is rigid enough for real cutting force; locked closed, it is safe to drop in a backpack, tool belt or glove box without a sheath. That dual use is explicitly part of Corona’s marketing, covering gardening, tree trimming, camping, biking and backpacking, and it is a meaningful advantage over a fixed blade saw that needs its own case to carry safely.
Build material and upkeep
High carbon steel is chosen for pruning saw blades because it holds a sharp edge through repeated cuts in green and dry wood alike, which is what Corona’s own description calls out directly. The trade off against stainless steel is reactivity to moisture, so a quick wipe down and an occasional light coat of oil after a wet job keeps rust from forming on the teeth, the same basic care any carbon steel garden blade needs. The folding pivot also benefits from staying free of sawdust and sap buildup so the lock continues to engage cleanly.
Alternatives to Consider
The Corona Tools Compound Action Anvil Lopper is the better choice for dead or dry branches within its cutting capacity, saving the saw for anything thicker. A fixed blade pruning saw with a longer blade is worth considering for a buyer who mostly works in the yard and does not need the folding portability. For true trunk cutting, neither a hand saw nor a lopper is the right tool, and a chainsaw is the appropriate step up.
Verdict
Buy the Corona RazorTOOTH 10-Inch Folding Pruning Saw for branches and limbs past lopper range, especially if it needs to double as a trail or camp tool. Skip it if the regular job is thick trunk material, which calls for a chainsaw rather than any hand saw at this blade length.

Corona RS16150B RazorTOOTH 10-Inch Folding Pruning Saw with Curved Steel Blade FAQs
A curved blade keeps more teeth in contact with the wood through each stroke, which generally cuts faster than a straight blade of the same length, at the cost of being a bit harder to resharpen evenly at home.
Corona markets this for branches, limbs and green or dry hardwood, and a 10 inch curved pruning saw typically handles limbs up into the 4 to 6 inch diameter range depending on wood hardness, well past what a lopper manages but short of trunk cutting.
Yes, the lock-back folding design is built to lock the blade fully closed for storage, the same safety concept used on folding pocket knives, which is why Corona markets it for camping and backpacking alongside yard work.
High carbon steel offers strong edge retention but is more reactive than stainless blades, so wiping the blade dry and adding a light coat of oil after wet use helps prevent surface rust over time.
