Jigsaw Blades vs Reciprocating Saw Blades: What Is the Difference?

Jigsaw blades are short, narrow blades for controlled cuts and curves in wood, laminate, plastic and thin metal. Reciprocating saw blades, often called Sawzall blades, are longer, thicker and built for rough, fast cutting in demolition, pruning and pipe work. They use different shanks, so one will not fit the other's saw.

The short version

Think of a jigsaw blade as a precision tool and a reciprocating saw blade as a demolition tool. The jigsaw rests on a flat base plate and follows a line, so its blade is slim enough to turn through curves. A reciprocating saw is held out in front of you and pushed into the work, so its blade is stiffer and sturdier.

Sawzall is a brand name that many people use for any reciprocating saw. When you see "jigsaw blades vs Sawzall blades," the question is really about these two blade families. The rest of this guide explains where they differ and how to choose between them.

How the two blades differ at a glance

The table below summarizes the main differences. Exact sizes vary by brand and by blade, so check the package for your specific saw and job.

Feature	Jigsaw blade	Reciprocating saw blade
Typical job	Curves, scrolls, clean edges	Demolition, rough cuts, pruning, pipe
Shank	T-shank on most modern saws, U-shank on older ones	Universal shank made for reciprocating saws
Body	Short and narrow so it can turn	Longer, wider and thicker so it resists bending
Cut quality	Fine and controlled	Fast and rough
Support	Flat base plate rides on the work	Shoe braces against the work, blade reaches in
Fits the other saw?	No	No

Shank and fit: why they will not swap

The first difference is the part you cannot see once it is installed: the shank. Most modern jigsaws take T-shank blades, and every blade on our jigsaw comparison page is a T-shank. Older saws may need U-shank blades, so check your manual or the old blade before buying.

A reciprocating saw uses its own universal shank and clamp. The jigsaw blade's tang is too small and the wrong shape for that clamp, and a reciprocating blade is too thick and wide for a jigsaw chuck. Even if you forced a blade in, it would not lock safely, so do not try.

Blade size, thickness and tooth design

Jigsaw blades are compact. In our jigsaw data, lengths run from 2.625 in for the shortest blade to 4 in for the longest. Shorter blades give you more control in thin material such as acrylic, while longer ones reach through thicker boards.

Tooth count also matters. Our jigsaw picks range from 6 TPI (teeth per inch) for fast wood cutting to 20 TPI for scroll cuts in laminate flooring. Fewer teeth cut faster and rougher. More teeth cut slower and cleaner.

Reciprocating blades follow the same logic, but they are built for harder abuse. They are longer and thicker because the saw's aggressive stroke would bend or snap a thin blade. Coarse teeth clear material quickly, while finer teeth suit metal. Specialty blades exist for specific jobs, such as masonry and buried roots.

Which blade for which job

Pick the blade by the material and the kind of cut you need, then match it to the right saw. These are the common cases:

Curves and scrolls in wood, laminate or plastic: jigsaw blade, with a finer tooth for a cleaner edge.
Clean top surface on a countertop or shelf: a reverse-tooth (down-cutting) jigsaw blade, which cuts on the downstroke and pushes splinters into the board.
Laminate flooring and melamine: carbide jigsaw blades, which last longer in hard, brittle sheets.
Plexiglas and acrylic: fine-tooth jigsaw blades made for plastic so the edge does not melt.
Tearing through framing, nails or old pipe: reciprocating blade.
Pruning branches or cutting through roots: reciprocating blade built for that work.
Cutting into masonry: reciprocating blade made for concrete.

Where to find the right blades

If your project is precise or curved, start with our best jigsaw blades comparison. It lists material, TPI, length and pack size side by side, including a coarse 6 TPI blade for fast wood cuts and fine 14 TPI to 20 TPI options for laminate and plastic.

If you are heading into rougher work, we also compare blades made for specific reciprocating jobs. See the best reciprocating saw blade for tree roots for yard work and the best reciprocating saw blade for concrete for masonry.

Band saws are a third option for long, straight or contour cuts on a bench. If that is closer to your project, compare the best band saw blades or the best band saw blades for metal.

Safety notes

Both saws can cause serious injury, and a few habits prevent most problems.

Unplug the saw or remove the battery before changing a blade, and let a used blade cool because it can be hot. Wear safety glasses, since broken blades and chips can fly. Reciprocating saws are loud, so wear hearing protection too.

Clamp your work so it cannot jump. Before cutting walls, floors or roots, check for hidden wires, pipes and nails. Cutting concrete and other masonry creates fine dust, so wear a proper dust mask and work with ventilation. When pruning at height, never cut while standing on an unsteady ladder.

Frequently asked questions

Can I use a reciprocating saw blade in a jigsaw?

No. The shanks and blade thickness are different, so a reciprocating blade will not lock into a jigsaw chuck. Always buy blades made for your specific saw.

Is a Sawzall the same as a reciprocating saw?

Sawzall is a brand name that many people use for reciprocating saws in general. Blades labeled for reciprocating saws fit the matching clamp, no matter which brand's saw you own.

Which saw is better for curved cuts?

A jigsaw. Its narrow blade and flat base plate let you follow a curve while keeping the cut controlled. A reciprocating saw is not made for that kind of steering.

How do I know if my jigsaw takes T-shank or U-shank blades?

Check the manual or look at the old blade. Most modern saws use T-shank blades, while older saws may need U-shank. A wrong shank will not lock in place.
