PowerLever Mechanism: The Key Innovation
The PowerLever mechanism is what separates the HS52 from standard hedge shears. Instead of traditional scissor geometry where you apply force at the handle and the blades meet at a fixed pivot point, the HS52 uses a compound lever system that concentrates your hand grip force and multiplies it at the cutting point.
Here's how it works in practice: when you squeeze the handles together, the mechanical advantage means you need roughly one-third the hand strength to generate the same cutting force. For someone with arthritis, weak hands after surgery, or simply returning to gardening after a long break, this transforms a frustrating task into something genuinely pleasurable. You can cut through fresh privet or boxwood stems without feeling like you're wrestling the shears.
The trade-off: the longer handle (27 inches total) takes up more storage space, and the slightly bulkier design means it won't fit into a typical garden tool belt loop. But for anyone doing serious hedge shaping—not just light trimming—the extra reach and power more than compensate.
Blade Quality & Cutting Performance
The HS52 uses hardened high-carbon steel blades, which is solid mid-range material. They're not as fine-grained as the SK-5 steel used in Japanese professional shears (like ARS), but they hold a respectable edge for 3-4 weeks of regular home use before needing sharpening.
In testing, the blades cut cleanly through:
- Privet: The classic hedge plant. The HS52 handles privet stems up to 3/8" without crushing, even late in the season when the wood is firmer.
- Boxwood: Denser than privet, boxwood tests your shear quality. The HS52 cuts it crisply when sharp; slightly slower when dull, but no crushing.
- Yew: Tougher than boxwood. This is near the upper limit of what the HS52 should tackle regularly. Thicker yew branches belong to a lopper.
- Spiraea and soft ornamentals: Where the HS52 really shines. The bypass action and clean cut mean no browning or disease entry on delicate new growth.
The bypass design (as opposed to anvil) ensures a clean, scissor-like cut that doesn't crush the stem. This is critical for plant health—bruised stems are more susceptible to fungal infection and heal slower. If you've ever seen browning or blackening at the cut edge of an ornamental shrub, that's typically an anvil shear or a dull blade doing damage.
Ergonomics & Hand Fatigue
At 18 ounces and 27 inches long, the HS52 sits in the middle ground: lighter and more compact than lopper-style shears, but longer than a pocket-sized bypass shear. The cushioned, contoured handles are designed to fit a right-handed grip naturally.
The spring tension (which automatically opens the blades between cuts) is well-balanced. It's not so tight that you fight it, but tight enough that it does the work of opening for you. This is where hand fatigue really shows up—a weak spring forces you to use thumb and finger strength to pry the shears open after every cut.
After 45 minutes of steady hedge shaping in our testing, the HS52 caused noticeably less hand fatigue than a standard $15 bypass shear. The PowerLever mechanism's mechanical advantage and the automatic spring combine to keep your hands fresher, letting you work longer and more precisely.
One note: the HS52 is NOT ambidextrous. Left-handed gardeners should specifically seek out the Fiskars HS-L52 (left-handed version). Using a right-handed shear in your left hand results in poor cutting performance because the blade geometry won't align correctly.

Pros, Cons & Who Should Buy
Pros:
- PowerLever mechanism delivers real power multiplication—noticeably easier cutting than standard shears
- Excellent value at $34–39 on Amazon; you get professional-level cutting ability for 1/3 the price of Bahco
- 27" length provides good reach along hedge faces and reduces bending
- Automatic spring return minimizes hand fatigue during extended work
- Hardened steel blades hold a decent edge; sharpening every 3–4 weeks is manageable at home
- Widely available on Amazon with same-day or next-day delivery in most US areas
- Lifetime warranty gives confidence in durability
Cons:
- Hardened steel doesn't hold an edge quite as long as professional-grade Swedish or Japanese steel (3–4 weeks vs. 6–8 weeks)
- 27" length is longer than compact pruning shears—won't fit easily into a tool belt or small hands
- Right-handed only; left-handed users must buy the separate HS-L52 model
- Not suitable for very thick woody stems over 3/8"—lopper or pruning saw recommended for heavier work
- The PowerLever mechanism, while excellent, adds slight weight compared to ultra-minimalist designs
Who Should Buy the Fiskars HS52:
- Homeowners with small to medium hedges (under 50 linear feet) doing regular maintenance
- Gardeners with arthritis, weak grip strength, or hand fatigue issues—the PowerLever mechanism is genuinely life-changing
- Anyone returning to gardening after a long break who wants power without a power tool
- Budget-conscious buyers who don't want to spend $70+ on professional-grade shears
- Topiary enthusiasts who value clean, precise cuts on delicate ornamental plants
Skip the HS52 if:
- You're left-handed (get the HS-L52 instead)
- You regularly cut through branches thicker than 3/8" (use a lopper instead)
- You work daily with hedges and need professional-grade edge retention (upgrade to Bahco or ARS)
- You have very small hands and need a compact design (look for 18–20" shears)
Maintenance & Care Tips
Sharpening: The outer bevel of each blade should be maintained at approximately 20–25 degrees. Use a whetstone or flat file, working from base to tip in smooth strokes. 10–15 strokes per blade is sufficient for regular maintenance. After sharpening, wipe both blades clean and apply a light oil (camellia oil is traditional, but any light machine oil works).
Between uses: Wipe the blades after each session to remove sap and plant debris. Dried sap accelerates dulling and can cause corrosion. A quick rinse under the garden hose followed by a dry cloth keeps the mechanism clean.
Storage: Keep the blade cover on when not in use. Store in a dry place—moisture accelerates rust on the steel, even though hardened steel is fairly corrosion-resistant. If you live in a humid climate, a light coat of camellia oil or 3-in-1 oil on the blades before long-term storage prevents oxidation.
Spring tension: The spring mechanism should open the blades automatically with minimal effort. If the spring weakens (usually after 2–3 years of heavy daily use), the shears are still functional but require more hand effort to open. Replacement is inexpensive on Amazon.
Storage and Weather Resistance
The Fiskars PowerLever HS52 is built from hardened high-carbon steel, which means it's reasonably weather-resistant but not stainless. Proper storage extends the life of your shears and keeps the blades sharp longer. Unlike electric hedge trimmers that require a garage and charging station, manual shears are easier to store—but they still benefit from a dry, protected environment.
If you live in a humid climate or near the ocean (where salt spray accelerates rust), store your HS52 in a shed, garage, or even indoors after each use. The blade cover that comes with the shears isn't just for protecting your fingers; it's essential for protecting the blades from moisture. Before long-term winter storage, apply a light coat of camellia oil or general-purpose machine oil to the blades. This creates a thin protective layer that prevents oxidation during months of dormancy.
For homeowners who leave their shears outside on a garden bench, invest in a locking wall-mount holder or a weatherproof storage box. Even a simple plastic bin with a desiccant packet ($5 at most hardware stores) keeps moisture at bay. The alternative—allowing rain and dew to sit on the blades—will cause visible rust patches within weeks, especially on the exposed cutting edges where the protective coating is thinnest.
One practical advantage of the HS52 is its relatively light weight (18 ounces). Unlike heavier professional shears that fatigue even experienced gardeners, you can comfortably keep the HS52 hung on a pegboard or stored in a garden tool cabinet without worrying about warping or structural strain. The contoured handles resist cracking better than cheaper plastic designs, even with temperature swings between winter and summer.
