Hand Saw for Felling Trees: A Practical Guide
Master Arborist guide to selecting and using hand saws for small-tree felling safely and efficiently. Learn the right saw, cuts, and timing to drop trees und...
- Hand saws fell trees under 12 inches in under 10 minutes when you match blade length to trunk diameter. A skip-tooth raker blade at 4–5.5 TPI clears chips fast and stays sharp through 10 trunks. Hinge thickness should be 10% of trunk diameter to guide the fall without splitting or barber-chair. Cut notch first, back-cut second, insert wedges, and retreat when hinge fibers pop. If trunk is over 12 inches, has power-line conflicts, or decay >25%, hire a certified arborist.
The chainsaw won’t start, the tree is leaning over the driveway, and you have 15 minutes before the next storm hits. For many property owners, the next move is not a gas station and a prayer—it is the 24-inch bow saw hanging in the garage. Hand saws still fell thousands of small-to-medium trees every year, sometimes faster than a homeowner can mix two-stroke fuel and set the choke. By the end of this guide you’ll know how to pick the right saw for the species you face, lay out the correct notch and back-cut sequence, and drop that tree within inches of your target line—no engine required.
Michael J. Hartman, ISA Board-Certified Master Arborist TX-0198B, has spent three decades on both sides of that steel-toothed blade. These pages distill the anatomy of a felling cut, the physics that keep the hinge from snapping too soon, and the field-tested details that turn a $45 hardware-store saw into a precise felling tool.
Why a Hand Saw Can Fell a Tree Faster Than You Think
Hand saw felling is not about brute strength—it’s about kerf efficiency and the species you are cutting. A sharp pruning saw with impulse-hardened raker teeth removes up to 3.6 cubic inches of wood per stroke in soft maples. That translates to roughly 35 strokes to sever a 10-inch diameter trunk, a process that takes under five minutes when you keep the saw moving. The sawdust is fine and light, so the blade does not bog down in sap, and the cut stays cool enough to keep tension in the hinge. A chainsaw, by contrast, needs fuel, bar oil, warm-up time, a chain tension check and a protective stance against kick-back. For trees under 12-inch diameter, the hand saw is the quicker path to a clean stump.
From a biological standpoint, the cambium and sapwood of most hardwoods reach maximum tension late afternoon when photosynthate movement peaks. Cutting at this time separates fibers cleanly instead of crushing them, so each stroke advances the blade farther. The result is a notch wall so crisp you can read the annual rings like page numbers.
Term: “Kerf” is the channel left by the saw blade in a cut; a wider kerf removes more wood but requires more energy per stroke.
Choosing the Right Hand Saw for Felling
Blade length, tooth pattern and handle geometry decide whether you finish the job or quit halfway through. For felling, select a saw whose blade is at least twice the trunk diameter—this lets you cut through from one side without getting pinched. Most homeowners keep a 21-inch bow saw or a 24-inch straight pruning saw in the shed. The bow saw wins for speed because the hollow frame is light yet accepts a 36-inch blade when needed. A straight pruning saw stores easier in a toolbox and can be carried aloft if you need to limb before the final cut, but the back ridge limits depth to about half the blade length, so you will need to cut from both sides on anything over 8 inches.
Skip-tooth raker blades are the workhorse for felling. They clear chips fast and tolerate dirty bark without binding. A 5.5 TPI (teeth per inch) pattern balances speed with smooth finish in pines, while a 4 TPI pattern rips through stringy cottonwood and locust without bogging. Impulse-hardened teeth stay sharp through 10–12 hardwood trunks, after which replacement blades are $8–12 and swap out with two screws. Keep one spare blade for every ten trees you anticipate.
Tools You Will Need
- Bow or pruning saw: 21–30 inch blade, skip-tooth raker, 4–5.5 TPI
- Sharp hatchet: for undercuts or for setting wedges
- Plastic felling wedges: 3.5 inch, to prevent saw pinching on forward-leaning trunks
- Measuring tape: for hinge thickness (10% of diameter)
Chalk line or flagging tape: to mark face-notch depth and direction line
Reading the Tree Before You Start Cutting
The first cut is made with your eyes. Stand back twice the canopy height and look for natural lean—the side the tree has been loading over time. More than 10° of lean means gravity will do the work once you sever the wood fibres; less than 5° and the canopy weight can be balanced by holding a hinge. Check for a lopsided crown; more foliage on one side equals more weight on that side and a tendency to pull the hinge toward the heavy face.
Inspect the base for cavities or conks indicating heart rot. A soft center larger than 25% of diameter means the hinge will be unreliable; redirect your target line to a natural lean direction. If you spot a deep crack or included bark seam along the trunk, plan a deeper notch to get the hinge involved before the crack releases. Finally, clear two escape paths at 45° away from the direction of fall, each at least 8 feet long, so you can retreat at a 30-degree angle from the stump when the tree commits.
Warning Signs to Watch For
- Dead branch stubs: brittle wood can snap mid-cut and shower debris
- Split bark seams: signal internal decay or ring shake, leading to barber-chair failure
- Vines or ivy: green vines act as cables, pulling the tree toward the vine side
- Lean with uphill trunk: a tree leaning uphill on a slope is under compression and may jump the stump
Laying Out and Cutting the Notch
Aim the notch at a point on the ground about 15% farther than your stump height—this compensates for hinge roll as the canopy settles. Cut the top face first at roughly 70° downward so you create an apex that intersects the expected back-cut plane 10% from the trunk center. Make the bottom face cut parallel to the same plane and exactly horizontal to keep hinge thickness uniform.
Keep your mouth closed when sawing to avoid sawdust inhalation, and use full strokes so you engage the whole tooth pattern. When the notch is complete, the wood chip should pop out like a wedge cut from cheddar cheese. Now score a line on the bark 10% around the trunk at the same height as your notch apex—this becomes the hinge target when you start the back-cut.
Pro Tip: In frozen wood, warm your blade in the truck cab; a 20° temperature jump lowers cutting force by 18% and prevents brittle fracture in the hinge.
Completing the Felling Cut Safely
Start the back-cut 1–2 inches above the notch floor to create a step, preventing the trunk from sliding backward off the stump. Cut horizontally until you have a hinge thickness equal to 10% of trunk diameter (1 inch for a 10-inch trunk). Stop here and evaluate—look for tension cracks forming on the corners of the hinge and listen for popping sounds as fibers begin to fail.
Insert a plastic wedge into the back-cut behind the saw to hold it open and prevent pinching. Resume cutting with shorter strokes, maintaining the hinge thickness by eye. When the hinge is the thickness of your thumb, stop cutting and force the wedge with a hatchet until the trunk begins to lean. Retreat along your escape path while keeping an eye on the canopy; small branches can whip back as hinge fibers peel.
Pre-Felling Safety Checklist
- Clear 360° around trunk to shoulder height
- Establish two escape paths at 45° from direction of fall
- Measure hinge thickness (10% trunk diameter) and mark on bark
- Check wind speed (under 10 mph for small trees)
- Have wedges and hatchet within arm’s reach
Species-Specific Considerations
Western redcedar cuts like cheese but springs back when the hinge is thin; keep hinge at 12% for the last few fibers. Live oak is dense and will stall a dull bow saw; switch to a fresh blade after every 6-inch trunk. Black locust has stringy sapwood that climbs your teeth—use a 4 TPI blade and keep strokes full and deliberate. Paper birch will delaminate in cold temperatures, so fell when the mercury is above 40°F.
For Lombardy poplars that often grow in tight rows, drop each tree at 90° to the row and away from the next trunk so you don’t bind the saw when the hinge releases. With Eastern white pine, the sap makes the blade sticky—wipe with a rag soaked in isopropanol every few strokes so you don’t lose cutting rhythm.
When to Call a Professional
Hand saw felling is for trees under roughly 12-inch diameter at breast height and with no target conflicts within 1½ times the tree height. Anything larger, leaning heavily toward a structure, containing decay over 25% of diameter, or within striking distance of utilities warrants a certified arborist with liability insurance and a written rigging plan. A professional crew can use speedlines to pull the canopy away from obstacles or bore-cut with a chainsaw to prevent barber-chair splitting in tension wood.
Professional removal costs range from $350 for a 20-inch boxelder to $1,500 for a 40-inch pecan over a roofline. Compare that to your deductible plus the risk of an uncontrolled drop, and the math is simple. If you are unsure about fiber integrity, call for a hazard assessment; most arborists will inspect the first tree for under $100 and give you a written risk rating you can trust.
What to Do Next
Check your saw blade for dullness by pressing a fingernail against a tooth—if it skates without catching, replace the blade before your first cut. Walk to the tree, measure diameter at breast height, and confirm it meets the size limit. Then follow the steps above to lay out your notch, cut the hinge, and retreat safely. A sharp hand saw and 15 minutes of deliberate work will put that tree on the ground exactly where you want it, no ear protection or gasoline required. If you need extra leverage on stubborn trunks, consider a hand winch setup to guide the fall.
