Hand saws
A chainsaw processes more wood per hour, but it needs fuel, maintenance, and a working engine. A hand saw needs neither. After a storm drops trees across your driveway, after a chainsaw that sat unused for 8 months refuses to start, and after the gas station queue is three hours long — a quality hand saw is what actually gets the road cleared or the firewood cut. Hand saws are the unglamorous backstop behind powered equipment, and the primary tool for anyone without a chainsaw budget or storage space.

This page is for educational purposes only. Hands-on skills should be learned and practiced under qualified supervision before relying on them in emergencies. Use this information at your own risk.
Three types cover the range of emergency and field use: bow saws for raw cutting speed on larger wood, folding saws for portability and pack use, and pruning saws for limb work in tight spaces. Knowing which one handles which task prevents buying the wrong tool and being surprised when it underperforms.
Bow saws
A bow saw consists of a metal tubular frame under tension that holds a replaceable blade — the same basic design that has processed firewood for centuries. The frame depth (the distance between blade and top bar) determines the maximum log diameter the saw can cut without the frame binding. A 21-inch (53 cm) bow saw with 5 inches (13 cm) of frame depth handles logs up to about 8 inches (20 cm) in diameter comfortably.
The Bahco 30-inch (76 cm) bow saw is a field standard for green wood cutting. Its blade uses a 4 TPI (teeth per inch) geometry designed with rakers — small chip-clearing teeth between the cutting teeth — that pull wet fiber out of the cut rather than packing it in. The result is a saw that doesn't bind in green wood the way a fine-toothed blade does. Dry wood and dimensioned lumber are better served by a 5–7 TPI blade with a finer tooth pattern.
Blade replacement: Most bow saw blades are replaceable and cost very little. A spare blade weighs under 4 oz (113 g) and stores flat. If you own a bow saw for emergency use, keep at least one spare blade. Blades dull over time, and a dull blade on green wood requires 40–60% more effort for the same cut.
Field note
Bow saws bind in green wood when the cut pinches the blade. Drive a wooden wedge into the kerf behind the blade as you cut through larger logs. A 1-inch (25 mm) piece of scrap wood driven in 4–5 inches (10–13 cm) behind the blade holds the kerf open and keeps the saw moving freely.
Frame portability: Bow saws are bulky. A 21-inch (53 cm) model doesn't fit in a standard pack. For vehicle kits and home workshops, this is irrelevant — the saw rides in the truck bed or hangs on the shop wall. For foot travel, a folding saw is more practical.
The Agawa Boreal 21 folding bow saw solves the portability problem: the frame folds flat to 26 inches (66 cm) and 1/2 inch (13 mm) thick, weighing 18 oz (510 g). It assembles in under 30 seconds and accepts standard 21-inch bow saw blades. For an emergency pack that might include both firewood processing and trail clearing, it's the best balance of saw performance and packability available.
Folding saws
A folding saw works on the same principle as a folding knife: the blade rotates into the handle for safe storage, then locks open for use. Folding saws designed for field use are not the same as contractor folding utility knives — a quality bushcraft folding saw uses a hardened, coarse-tooth blade 9–11 inches (23–28 cm) long that cuts wood aggressively.
The Bahco Laplander is the benchmark. Its 9-inch (23 cm) blade uses 7 TPI XT-geometry teeth that cut on both push and pull strokes, reducing effort on each pass. It handles green or dry wood up to 5–6 inches (13–15 cm) in diameter. Closed length: 9.6 inches (24 cm).
Weight: 5.6 oz (159 g). For a bug-out bag, get-home bag, or general pack, this is the folding saw that earns its weight.
The Silky Pocketboy (6.7-inch / 17 cm blade, 5.6 oz (159 g)) cuts on the pull stroke only but does so extremely fast — the 7.5 TPI impulse-hardened blade outperforms most Western-style folding saws in wood removal per stroke. Japanese pull-cut geometry takes adjustment if you're used to push saws, but the results are faster in both green and dry wood.
For larger logs, the Silky Gomboy (9.5-inch / 24 cm blade) or a 14-inch (36 cm) folding saw bridges the gap between a compact folder and a full bow saw. These handle 8–10 inch (20–25 cm) diameter logs with manageable effort, at weights between 8–12 oz (227–340 g).
Folding saw lock mechanism
Always confirm the blade is locked open before cutting. Most quality folding saws use a liner lock or spine lock — the blade should not move when you push sideways on it while open. A folding saw blade that closes during a cut will cause a serious hand laceration. If the lock feels loose or the blade moves under lateral pressure, do not use the saw.
Pruning saws
A pruning saw is designed for living wood: branches, limbs, and green growth. The blade is typically straight or slightly curved, with a coarse pull-cut tooth pattern optimized for green wood fiber. They excel at removing storm-damaged limbs from trees, clearing brush from trails, and the kind of overhead cutting that bow saws and folding saws handle awkwardly.
Most pruning saws fold like a large folding saw, with blades between 8–14 inches (20–36 cm). A curved blade improves the cut angle for overhead limbs. Look for a model with a lockback mechanism rated to hold under the lateral load of pulling a blade through a green limb — this is where low-end pruning saws fail.
For larger limb work, a pole saw — a pruning saw head on an extendable aluminum handle — eliminates climbing. Telescoping models reach 8–12 feet (2.4–3.7 m). The tradeoff is less control over the cut and more effort per stroke, but the safety advantage of keeping feet on the ground is real.
TPI selection guide
Tooth-per-inch count is the single most important blade specification. TPI determines how the blade interacts with the material — coarse teeth clear chips quickly in green or fibrous wood; fine teeth cut slower but leave a cleaner kerf in dense or dry material.
| TPI | Best for | Avoid for | Field example |
|---|---|---|---|
| 3–5 | Green wood, large-diameter logs (8 in (20 cm)+) | Dry wood, precise cuts | Bow saw on fresh-felled firewood |
| 5–7 | General use, mixed green and dry | Very fine joinery work | General camp saw, trail clearing |
| 7–10 | Dry wood, dimensional lumber | Green or wet wood (binds) | Pruning saw on dry limbs, rough carpentry |
| 10–14 | Fine woodworking, joinery | Firewood, green wood | Tenon saw, dovetail work |
| 18–32 | Metal, plastic, PVC pipe | Wood of any kind | Hacksaw blades |
An emergency firewood saw wants 4–5 TPI. A general-purpose field saw wants 7 TPI. A pack saw for varied conditions should split the difference at 7 TPI, which handles both green and dry wood adequately.
Raker teeth: Some bow saw blades add raker teeth — small, flat-topped teeth interspersed between cutting teeth — that scoop chips out of the kerf rather than packing them in. Rakers make a significant difference on green, sappy wood (pine, spruce, fresh-cut hardwood). Look for raker geometry on any blade intended for green firewood work.
Crosscut versus rip saw technique
Hand saws fall into two categories based on tooth geometry — and using the wrong type for the job is the fastest way to produce a rough cut or a bound blade.
Crosscut: Teeth are beveled to slice across wood fibers like a row of knife points. Most field saws are crosscut. Use crosscut geometry when sawing across the grain of a log or board — bucking rounds from a log, cutting framing lumber to length.
Rip saw: Teeth are filed straight across (like tiny chisels) and designed to split wood fibers along the grain. Rip saws cut dramatically faster when working with the grain but produce a ragged exit wound when used across it. Bow saws with raker geometry approximate a ripping action in green wood.
Technique differences by cut type:
For crosscuts (across the grain): 1. Mark the line and score it with two light strokes, barely touching 2. Start the cut on the pull stroke, using the teeth nearest the handle to establish the kerf 3. Progressively extend to full-blade strokes once the kerf is established — this prevents the blade from skipping off the mark 4. Keep the saw at 45–60° to the wood surface; shallower angles bind, steeper angles skip
For ripping (with the grain — less common in field use): 1. Set the saw at a low angle (20–30°) to the wood surface — rip cuts are always at a shallow angle 2. Use slower, heavier strokes; ripping is always more work than crosscutting 3. Insert a wedge into the kerf early — rip cuts close on themselves as internal tension releases
Branch and limb removal: When removing a branch from a standing tree, make a relief cut from below first (one-third of the diameter), then complete from above. Without the relief cut, the weight of the branch will close the kerf as you cut and bind the blade — or strip the bark in a long split when the branch falls.
Cutting technique
Efficiency with a hand saw depends on body position and stroke mechanics, not effort. Forcing a saw — pressing hard and taking short strokes — binds the blade and tires you out. Let the teeth do the work:
- Score the cut line with two or three light strokes before applying full pressure
- Use the full blade length on every stroke — 18-inch (46 cm) strokes on a 21-inch saw, not 6-inch (15 cm) chops
- Keep the cut perpendicular to the log; an angled blade creates friction on the sides
- Let blade weight do the downstroke; apply gentle downward pressure on the return
- On green wood over 6 inches (15 cm) diameter, insert a wedge into the kerf after 3–4 inches (8–10 cm) of cut depth
A skilled person with a quality bow saw can process 4–6 inch (10–15 cm) diameter firewood rounds at a rate of roughly one per minute. Pace that expectation: cutting a cord of firewood by hand is a half-day of serious work, not an afternoon.
Maintenance
Saw blades dull faster than most people expect. A blade that cuts well today will be noticeably slower after 2–3 hours of green wood work. Most field saws use hardened teeth that cannot be field-sharpened with basic tools — once dull, the blade is replaced, not restored.
Blade replacement economy: Bow saw blades cost very little and store flat. Keep two spare blades. Folding saw blades on models like the Bahco Laplander are replaceable; a replacement blade costs a fraction of the saw's price.
Cleaning: Sap and pitch build up on blades and increase friction dramatically. Wipe blades with mineral spirits or a dedicated pitch remover after any session on pine, spruce, or other resinous wood. Store with a light coating of oil.
Handle inspection: Wooden handles on traditional bow saws absorb moisture and crack. Inspect annually and apply a light coat of linseed oil to prevent cracking. Synthetic handles (fiberglass, plastic) need no maintenance.
Saw maintenance frequency schedule
| Task | Frequency | Notes |
|---|---|---|
| Wipe blade, apply light oil | After every use | Prevents pitch buildup and rust |
| Clean pitch and resin | After every resinous wood session | Mineral spirits or dedicated pitch remover |
| Inspect blade set (tooth lean) | Every 5–10 hours of use | Look for teeth leaning the same direction — indicates the set is gone |
| Replace bow saw blade | Every 8–15 hours of cutting | Earlier if blade smokes or requires heavy force |
| Replace folding saw blade | Every 15–25 hours of cutting | Most brands sell replacement blades inexpensively |
| Inspect frame welds and joints | Annually | Look for cracks at the tension tube connections on bow saws |
| Oil wooden handles | Annually (or if handle looks dry) | Boiled linseed oil, one coat, let dry 48 hours before use |
Setting and sharpening panel saws (non-hardened blades)
Traditional panel saws — fixed-plate hand saws with non-hardened teeth — can be sharpened and re-set, a skill worth knowing for any hand saw intended for long-term use. This does not apply to modern hardened-tooth bow saw or folding saw blades, which cannot be dressed with standard files.
Saw set refers to the amount the teeth are bent alternately left and right of the blade centerline. Proper set creates a kerf slightly wider than the blade thickness, preventing binding. Over time and sharpening, the set is reduced and the saw begins to bind.
To re-set: 1. Clamp the saw plate in a vise, teeth up, at working height 2. Use a saw set tool (an inexpensive dedicated tool) to bend every other tooth to the left; rotate and bend the remaining teeth to the right 3. Set depth: for a general-purpose panel saw on dry wood, 0.010–0.015 inches (0.25–0.38 mm) of set per side is functional
To sharpen: 1. Secure the saw in the vise; illuminate the teeth with a light source angled to show reflections 2. Use a triangular taper file (appropriate size for the TPI — typically 6-inch / 15 cm for 8–10 TPI saws) 3. File each tooth at the original bevel angle (typically 65–75° to the plate for crosscut geometry); maintain consistent pressure and file count per tooth 4. Alternate sides: file one tooth, skip the next; rotate and file the skipped teeth 5. A sharp tooth has no reflective flat on its tip — it terminates in a point
After sharpening, run the flat of a stone lightly along both sides of the blade to remove burrs, then apply oil before storage. A freshly set and sharpened panel saw cuts significantly cleaner than a new low-cost saw from a box store.
Checklist
- Own at least one bow saw (21-inch / 53 cm minimum) with one spare blade for home and vehicle use
- Include a folding saw (Bahco Laplander or equivalent, 7 TPI) in each pack and vehicle kit
- Match blade TPI to primary use: 4–5 TPI for green firewood, 7 TPI for general field use
- Test the blade lock on any folding saw before every use; replace if the lock feels loose
- Stock pitch remover or mineral spirits for cleaning after work on resinous wood
- Practice full-stroke technique — score first, full blade length on every stroke, wedge green logs
Saws complement axes in the firewood-processing workflow: an axe splits rounds that a saw bucks from a log. The two tools together handle the full sequence from tree to stove-length wood without requiring powered equipment. For processing significant volumes of storm-damaged wood or building material, see chainsaw for when powered tools become worth the complexity. When saws are used for joinery rather than rough cutting — cross-cuts, tenons, and frame work — see carpentry for the technique and layout methods that apply.
