A jigsaw is a handheld power saw that uses a narrow blade moving up and down to cut curves, shapes, notches, and straight lines in wood, plywood, laminate, plastic, and some thin metals when using the correct blade.
For homeowners, a jigsaw is often one of the first power saws worth owning because it is versatile, relatively approachable, and useful for projects where a circular saw is too big or cannot cut curves.
How a Jigsaw Works
A jigsaw has a small blade that moves rapidly in a vertical motion. You guide the tool along a marked line while the flat base, called the shoe, rests on the material.
Common parts include:
- Blade – Removable cutting blade selected by material and cut type
- Shoe / base plate – Sits flat on the workpiece
- Trigger – Controls power and speed
- Orbital setting – Makes cutting more aggressive on some models
- Blade clamp – Holds the blade in place
- Bevel adjustment – Allows angled cuts on some models
What a Jigsaw Is Best Used For
Best for:
- Curved cuts
- Cutouts in plywood or panels
- Sink cutouts in countertops with the right blade and method
- Notches around obstacles
- Cutting thin boards
- Craft and DIY projects
- Roughing out shapes
- Cutting laminate or plastic with the right blade
Not great for:
- Perfectly straight long cuts without a guide
- Thick framing lumber
- Fast repetitive cuts
- Heavy demolition
- Precision cabinet-grade cuts without cleanup
How to Choose a Jigsaw
Doing basic DIY projects?
Use a corded or cordless jigsaw with variable speed and tool-free blade change.
Already own cordless tools?
A cordless jigsaw in your battery platform is convenient, especially for small projects away from outlets.
Want smoother cuts?
Choose a jigsaw with variable speed, a solid shoe, low vibration, and the correct blade. The blade matters as much as the saw.
Cutting curves often?
Look for good visibility around the blade and smooth control. Smaller/narrower blades turn tighter curves.
Choosing Jigsaw Blades
Wood blade, lower TPI
- Faster cut
- Rougher edge
- Good for construction or rough work
Wood blade, higher TPI
- Slower cut
- Cleaner edge
- Better for finish work
Reverse-tooth blade
- Helps reduce splintering on the top surface
- Useful for laminate or finished plywood
Metal blade
- Higher TPI
- Used for thin metal with slower speed
Specialty blades
- Available for plastic, laminate, tile, and other materials
How to Use a Jigsaw
Choose the right blade
Match the blade to the material and desired cut quality.Clamp the material
The workpiece should not bounce or vibrate.Mark your cut line
Use a pencil, square, or template.Start with the shoe flat
Let the blade reach speed before entering the cut.Guide steadily
Do not force the saw. Let the blade cut.Use relief cuts for tight curves
This keeps the blade from bending.Support the cutoff
Prevent the last piece from snapping or splintering.
Common Mistakes
- Using the wrong blade – Most bad jigsaw cuts are blade problems.
- Forcing the saw – This bends the blade and creates angled cuts.
- Not clamping the work – Vibration ruins accuracy.
- Expecting table-saw straightness – Use a guide or choose a different saw.
- Cutting finished material from the wrong side – Splintering often happens on the top surface depending on blade type.
Recommendations
DIY / Budget Friendly Recommendation
A basic corded jigsaw with variable speed is affordable and capable for most homeowners.
Best for:
- Occasional projects
- Curves
- Notches
- Plywood cutouts
- Light woodworking
Best Value Recommendation
A cordless jigsaw in your existing battery platform is the most convenient choice if you already own cordless tools.
Look for:
- Tool-free blade change
- Variable speed
- Bevel-capable shoe
- Good blade visibility
- Low vibration
Prosumer Recommendation
For frequent use, choose a jigsaw with excellent blade control, smooth orbital settings, dust blower, and a sturdy shoe. Better jigsaws cut more accurately because they vibrate less and keep the blade tracking straighter.
Fixers Club Tip
A jigsaw is the right saw when the shape matters more than speed. For long straight cuts in plywood, use a circular saw with a guide. For curves, cutouts, and notches, reach for the jigsaw.
