Even in an era dominated by power tools, the humble handsaw remains an indispensable tool in every carpenter’s kit. From precise joinery cuts on site to quick adjustments in tight spaces where a circular saw cannot reach, understanding how to select, maintain, and use handsaws properly can significantly improve the quality and efficiency of your woodworking projects. While modern builders have access to a wide array of construction tools available to modern builders, the handsaw occupies a unique place as a tool that demands skill, care, and knowledge to use effectively. This comprehensive guide covers everything you need to know about handsaws from understanding the different types to keeping them razor sharp.
Understanding Handsaw Types and Their Applications
Not all handsaws are created equal. Choosing the right saw for the task at hand depends on the type of cut you need to make and the material you are cutting. The two primary categories are crosscut saws and ripsaws, each designed with specific tooth geometry for different cutting directions.
Crosscut Saws vs. Ripsaws
A crosscut saw is designed to cut across the wood grain. Its teeth act like a row of small knife points, severing the wood fibers cleanly as they pass through the material. Crosscut saws typically have finer teeth ranging from 7 to 12 points per inch (PPI). A 7-point crosscut saw is suitable for rough framing lumber, while an 11 or 12-point saw produces the smooth finish needed for fine trim work and cabinetry.
A ripsaw, by contrast, is designed to cut along the grain. Its teeth work like small chisels, removing tiny chips of wood as the saw advances through the cut. Ripsaws have larger teeth with deeper gullets between them and typically feature 4.5 to 6 points per inch, with 5.5 points being the most common configuration. While you can rip with a crosscut saw in a pinch, crosscutting with a ripsaw produces poor results and should be avoided.
Handsaw Configurations
Beyond tooth pattern, handsaws vary in length, blade shape, and handle design. Most full-size handsaws measure about 26 inches long. Shorter saws measuring 22 to 24 inches are called bench saws or panel saws and are ideal for workshop use where space is limited. The top edge of the saw, known as the back, can be either straight or skewed. Skew-back saws taper from the handle to the toe in a gentle S-curve and were particularly popular in the early 20th century. They offer better maneuverability for curved cuts. However, square-back saws serve as useful straightedges and allow you to scratch a square line across the blade for marking.
| Saw Type | Points Per Inch | Cut Direction | Best Use | Tooth Action |
|---|---|---|---|---|
| Crosscut | 7-12 PPI | Across grain | Trim work, framing, general cutting | Knife points sever fibers |
| Ripsaw | 4.5-6 PPI | Along grain | Ripping lumber, resawing | Chisel points remove chips |
| Panel Saw | 10-12 PPI | Across grain | Fine joinery, precise cuts | Fine knife points |
| Carcase Saw | 12-14 PPI | Across grain | Dovetails, tenons, joinery | Very fine knife points |
Selecting a Quality Handsaw
A quality handsaw is an investment that, with proper care, can last for decades. The key factors to evaluate when selecting a saw include blade steel quality, tooth geometry, handle ergonomics, and overall balance. Understanding the essential construction tools for professional carpenters helps contextualize where a well chosen handsaw fits into your broader toolkit.
Blade Quality and Material
Traditional handsaws were made from high carbon steel, which takes a sharp edge well and holds it through extended use. Vintage saws from manufacturers like Disston, Atkins, and Sandvik are prized for their superior steel quality. Modern saws often use hardened steel that stays sharp longer but is more difficult to sharpen by hand. When inspecting a blade, check for straightness by sighting down the length of the saw. Any warp or twist will make accurate cutting difficult regardless of how sharp the teeth are.
Handle Comfort and Grip
The handle, traditionally made from applewood, beech, or rosewood, should fit comfortably in your hand. Look for a handle with a well defined pistol grip that allows your forearm to align naturally with the blade. Poorly designed handles cause hand fatigue and reduce cutting accuracy. Many vintage saws feature detailed handle carvings that provide excellent grip even when your hands are sweaty or dusty.
Restoring an Old Saw
Some of the best handsaws available are vintage finds from flea markets, estate sales, or antique shops. Restoring an old saw requires several steps:
- Clean the blade thoroughly with mineral spirits and fine steel wool to remove rust and pitch buildup
- Sand the blade surfaces lightly with 220 grit sandpaper to remove pitting, then polish with 400 grit
- Apply a thin coat of paste wax to protect the blade from future rust
- Refurbish the handle by sanding and applying boiled linseed oil or shellac
- Joint, shape, set, and sharpen the teeth before use
Handsaw Sharpening: Jointing, Shaping, Setting, and Filing
Sharpening a handsaw is a skill that every carpenter should develop. A sharp saw cuts with minimal effort and produces a smooth surface that requires little sanding. The sharpening process follows four distinct steps performed in order. Regular proper saw blade maintenance and cleaning between sharpenings will extend the life of your saw and maintain cutting performance.
Jointing
Jointing is the process of lightly filing the tops of the teeth so they all reach the same height. Place the saw in a vise with the teeth facing up. Run a mill file flat along the tops of the teeth until every tooth tip shows a small flat spot. This ensures that all teeth are equal height and share the cutting load evenly. A well jointed saw cuts straight and does not wander in the kerf.
Shaping
After jointing, the teeth must be reshaped to restore their proper geometry. For crosscut saws, each tooth has a face and a back that meet at a sharp point. The face angle for crosscut teeth typically ranges from 12 to 15 degrees relative to a line perpendicular to the blade. Ripsaw teeth have a more aggressive face angle of about 8 degrees, with a square front edge that acts like a chisel. Use a triangular saw file of the correct size for your tooth pitch to reshape each tooth to its proper profile.
Setting
Setting refers to bending alternate teeth slightly outward to opposite sides of the blade. This creates a kerf wider than the blade thickness, reducing friction and preventing the saw from binding in the cut. Use a saw set tool, which registers on the tooth and bends it by a consistent amount. The set should be uniform across all teeth. Too much set makes the saw cut roughly and waste more wood; too little set causes the saw to bind and overheat. A good rule is to set the teeth to about one third of the blade thickness on each side.
Filing the Final Edge
The final sharpening step involves filing each tooth to a keen edge. For crosscut saws, file at an angle of about 60 degrees to the blade face, cutting from the outside toward the center of the saw. This creates the knife edge that severs wood fibers. For ripsaws, file straight across the tooth face at 90 degrees to the blade, creating the chisel edge that scoops out wood chips. Use steady, even pressure and take the same number of strokes on each tooth. Apply gentle pressure on the forward stroke and lift the file on the return.
- Joint the tooth tops flat with a mill file until all teeth show a uniform flat spot
- Shape each tooth to proper profile using a triangular saw file matching tooth pitch
- Set alternating teeth to opposite sides using a saw set tool
- File the final cutting edge: 60 degrees for crosscut, 90 degrees for rip
Proper Handsaw Techniques for Accurate Cuts
Even the sharpest handsaw produces poor results without proper technique. Learning to use a handsaw effectively involves understanding body position, grip, stroke mechanics, and work holding. The art of traditional woodworking and furniture making relies heavily on these foundational sawing skills.
Body Position and Grip
Stand with your feet shoulder width apart and your shoulder aligned with the cut line. Your body should face the work, not the saw. Hold the handle with a relaxed grip, wrapping your fingers around the handle with your index finger pointing along the blade direction. This pointing finger helps guide the saw naturally. The cutting stroke comes from your shoulder and upper arm, not your wrist. Let the weight of the saw do most of the work, applying only light downward pressure.
Starting the Cut
Starting a cut accurately is the most critical phase of handsawing. Place your thumb against the side of the blade near the toe to guide the first few strokes. Draw the saw backward gently two or three times to establish a shallow kerf. Once the kerf is established, remove your thumb and begin full strokes. Keep the saw at a 45 degree angle to the work surface for general cutting, or adjust to 60 degrees for faster but rougher cuts. For fine joinery, use a shallow 30 degree angle for maximum control.
Maintaining the Cut Line
Once underway, focus on three things: keeping the blade perpendicular to the work surface, following your marked line, and maintaining a steady rhythm. Use your eyes to sight down the blade and check alignment with your layout line every few strokes. If the saw starts to wander, do not force it back. Instead, twist the blade slightly in the kerf to redirect it gradually. Watch for these common problems:
- Saw binding in the cut: the set may be insufficient or the blade may have burrs
- Cut wandering off line: you may be applying uneven pressure or the saw may be dull
- Excessive effort required: the saw likely needs sharpening or the tooth set is wrong
- Rough cut surface: the teeth may be over set or the file work was uneven
- Blade overheating: you may be pushing too hard instead of letting the saw cut
Finishing the Cut
As you near the end of the cut, the waste piece begins to sag and may tear out if not supported. Slow your stroke pace and use lighter pressure. Support the waste piece with your free hand or a workbench support. For long rips, insert a thin wedge into the kerf behind the saw to prevent binding and keep the kerf open. A well executed finish leaves a clean edge with no splintering on either side of the cut line.
