The short version: buy the Milwaukee M18 FUEL Sawzall 2821-20, bare tool, on the M18 batteries you own or are about to. It's the saw the trades actually carry — enough power for cast iron and nail-embedded framing, light enough for overhead work, with a blade clamp built to survive wet demo and a 5-year warranty. Already on DeWalt or Ryobi batteries? Stay there — the platform decides it, and I cover both below.
Raw cut speed is stroke length times strokes per minute, and nearly everything decent now runs about 1-1/4" at 3,000+ SPM — so the big number on the box tells you almost nothing. A reciprocating saw is a fatigue tool: it shakes, you hold it, and an hour of demo settles the argument. What actually separates the tiers is vibration control (a counterbalanced mechanism versus your hands eating the shake), the blade clamp (does it still open after wet, gritty cast-iron cuts, or does it corrode shut), orbital action (an aggressive wood-cutting mode the premium saws add), and form factor (full-size two-hander versus one-handed compact). Buy for your forearms, not the spec sheet.
The picks — good, better, best
Picked by Al, the Building Doctor
IUOE Local 39 Stationary Engineer (2001) · 30+ years across hospitality, Class A retail, and senior living. Personal: a full-size M18 Sawzall for tear-out, and a box of good blades that matters more than either saw.
Every recip saw cuts on day one. The question is what your hands feel like after an hour of overhead demo, and whether the blade clamp still opens after you've cut a water-filled drain pipe. I pick for the forearms — and I put the saved money into blades.
Milwaukee M18 FUEL Sawzall (2821-20)
Bare tool — no battery or charger in the box. Brushless, 1-1/4" stroke at 0–3,000 SPM, adjustable shoe, rafter hook — and the detail that matters: a stainless-hardened QUIK-LOK blade clamp, the gen-2 fix for the old clamp that corroded shut after wet cast-iron cuts. Backed by the deepest blade ecosystem in the trade and a 5-year warranty.
Tradeoff: no orbital action (Milwaukee saves that for the Super), and M18 entry cost stings if you're not already on the platform.
Best for: almost everybody doing real demo — it's the saw the trades carry daily.
Ryobi ONE+ HP 18V Brushless (PBLRS02B)
Bare tool — pairs with the Ryobi ONE+ batteries you may already own. Brushless, 1-1/4" stroke at 0–3,200 SPM, pivoting non-marring shoe, LED, tool-free blade lever — and it won the reciprocating-saw category at the 2025 Pro Tool Innovation Awards, with up to 470 cuts per charge claimed.
Tradeoff: no orbital mode and no counterbalance — vibration is manageable, not premium. Home Depot–ecosystem batteries only.
Best for: the homeowner on Ryobi ONE+ who does a few demo weekends a year.
A reciprocating saw is a bare-tool purchase: if you already own cordless batteries, buy the saw that clicks onto them and skip my brand argument entirely. Already on DeWalt 20V MAX? Get the DeWalt DCS386B FlexVolt Advantage — 1-1/8" stroke, 0–3,000 SPM, and roughly 50% more power when you feed it a FlexVolt pack. Need one hand free — overhead rough-in, pipe under a sink, tight mechanical spaces? That's the one-handed compact class: the Milwaukee M18 FUEL Hackzall 2719-20 (7/8" stroke, dual-gear counterbalance, a claimed 4x less vibration). Ryobi makes a one-handed equivalent too, the PSBRS02B. The platform is the real long-run cost — the saw is just the next tool on it.
Milwaukee covers the 2821-20 and 2722-20 with a 5-year limited warranty on M18 tools, no registration required. Ryobi backs the PBLRS02B for 3 years plus a 90-day exchange. The DeWalt alternative carries 3 years plus 1 year of free service and a 90-day money-back window. All of it hinges on where you bought the tool — see the box below. How to actually get a claim honored →
Milwaukee has zero authorized dealers on Amazon — not one — and it won't honor the warranty on gray-market or counterfeit units, a point ToolGuyd has documented at length. DeWalt is a known counterfeit-target brand too. My links go to Amazon search results on purpose: check the seller before you buy, or just buy the tool from Home Depot, Acme Tools, or Ohio Power Tool and be done with it. And batteries only from an authorized dealer, full stop — counterfeit packs look convincing and are a documented fire risk. A marketplace "deal" on a red battery is not a deal.

Milwaukee 2821 vs 2722 (Sawzall vs Super Sawzall) — and where the Ryobi fits
The model-number question everyone on M18 actually asks. Here's the quick compare, then the honest answer.
| Ryobi PBLRS02B Good | Milwaukee 2821-20 The one I'd buy | Milwaukee 2722-20 Best | |
|---|---|---|---|
| Stroke & speed | 1-1/4" · 0–3,200 SPM | 1-1/4" · 0–3,000 SPM | 1-1/4" · 3,000 SPM, 5-speed dial |
| Orbital action | No | No | Yes — selectable on/off |
| Vibration | Manageable, no counterbalance | Low for a full-size | Counterbalanced — but heavy |
| Blade clamp | Tool-free lever | Stainless-hardened QUIK-LOK | QUIK-LOK |
| Weight class | Lightest | The everyday carry | Heaviest; wants a High Output pack |
| Warranty | 3-year + 90-day exchange | 5-year | 5-year |
| Best for | Ryobi ONE+ demo weekends | Almost everyone — the trades' carry | Gut-to-the-studs remodels |
The honest answer: the 2821-20. The Super's extra grunt and orbital mode matter maybe 5% of the time; the 2821's lighter weight matters every time you lift it over your head. Buy the 2722-20 when the job is measured in rooms, not boards — and buy the Ryobi when the honest answer to "how often?" is a few weekends a year on batteries you already charge.
Honest about the trophies, because they don't all point at my verdict. The 2025 Pro Tool Innovation Award for reciprocating saws went to the budget pick here — the Ryobi PBLRS02. Pro Tool Reviews' lab head-to-head crowned the Makita 40V XGT best overall and the Metabo HPT 36V best value — those are the lab picks, and they're real saws. And Lifestory Research's 2026 most-trusted power-tool-brand study puts DeWalt first with Milwaukee fourth. So why carry the Milwaukee? Because "best in the lab" and "what I'd carry" are different questions. Milwaukee engineers invented this tool in 1951 — it's in JLC's tool Hall of Fame — its blade ecosystem is the deepest going, and 75 years on it's still the saw on the trades' tailgates. I'd rather tell you the trophies straight than pretend my pick won them all.

Representative of owner reviews & trade-forum sentiment — paraphrased and source-typed, not republished.
Read enough reviews and forum threads and the pattern is unmistakable. The five-star reviews are all about power: cuts through anything, corded-class confidence, quick blade changes. The one-star threads are almost never about power — they're about the things no spec sheet mentions: weight and vibration fatigue on long jobs, blade clamps seizing after wet, gritty cuts, and stock blades that make a good saw feel gutless. That's the whole reason my verdict weights vibration and the clamp over another 200 SPM.
The other thread that keeps me honest: on old cast iron, working plumbers often reach for an angle grinder first and use the recip saw only where sparks would be dangerous — and they buy Lenox or Milwaukee Torch demolition blades by the sleeve, expecting to burn one per cut. The tool is beloved; the pros just pair it with the right blade and the right expectations.
How I actually shop for a reciprocating saw — and why the blade matters more than the saw
I shop for the hour mark, not the first cut. Every saw on this page severs a 2x4 on day one; the differences show up forty minutes into overhead demo, when a counterbalanced saw is still just loud and an uncounterbalanced one has your hands buzzing. That's the fatigue wedge, and it's why I'll take the lighter 2821 over the stronger Super for everything short of a gut job.
Then there's the part almost every buyer gets backwards: the blade matters more than the saw. A cheap stock blade makes a premium saw feel weak, and a proper demolition blade makes a budget saw punch above its class — so swap the damn blade before you blame the tool. Three blades cover nearly everything a house throws at you: a bi-metal demolition blade (6–10 TPI) for wood with nails in it, a metal blade (14–18 TPI) for pipe, rod, and bolts, and a pruning blade (around 5 TPI) for the yard. That three-blade starter kit is the best money on this page.
When I'm standing at the rack, here's the whole checklist:
- Buy bare-tool on the battery platform you already own — the platform is the purchase; the saw is an accessory to it.
- Weight and vibration over SPM — pick it up, run it if the store lets you. Your forearms are the test lab.
- A blade clamp you'd trust wet — tool-free, and ideally stainless-hardened; a seized clamp strands the whole tool.
- Orbital action only if demo is your life — it's a wood-speed feature; it does nothing for metal.
- Spend the savings on blades — demo 6–10 TPI, metal 14–18 TPI, pruning ~5 TPI.
Sawzall vs reciprocating saw — is there a difference?
No — and yes, in the way that matters at the register. Sawzall® is Milwaukee's registered trademark, the name it gave the first portable electric reciprocating saw its engineers built in 1951, and the name went generic the way Kleenex did. Every brand makes a reciprocating saw; only Milwaukee makes a Sawzall. When your uncle says "grab the Sawzall," he means whatever recip saw is within reach — but when a listing says Sawzall, it should have a red tool in it. Same tool, one brand's name, 75 years of the name doing the advertising. (Plenty of folks also say "recip saw" or "demo saw" — all the same machine.)
Sawzall vs Hackzall — full-size or one-handed?
This is a sizing decision, not a brand one. The full-size saw (Sawzall class) wants two hands and gives you the long 1-1/4" stroke — that's demolition, decks, fence posts, pruning. The one-handed compact (Hackzall class) runs a shorter 7/8" stroke in a body you can hold overhead or slip under a sink — that's pipe rough-in and tight mechanical spaces, and the 2719-20 version adds a dual-gear counterbalance that makes it strangely smooth. Buy the full-size first. Plumbers and electricians often carry both; homeowners almost never need the compact before the big one.
What does orbital action do on a reciprocating saw?
Orbital action swings the blade in a slight ellipse instead of a straight back-and-forth, so each stroke claws out more wood — dramatically faster cutting, noticeably rougher edges. It's the feature that separates premium demo saws (like the Super Sawzall) from standard ones. The rule: orbital on for wood and demo, orbital off for metal — steel and cast iron want a flat, straight stroke, and an ellipse just chatters and eats blades. If your work is pipes and rods more than studs and decks, you can skip the feature entirely and save the weight.
Who actually uses these — and what that tells you
Demolition and remodeling is the signature trade: wall tear-out, layered drywall-and-stud cuts, nail-embedded lumber that would wreck a circular-saw blade. But the tell is how many other trades carry one daily:
- Remodelers & demo crews — tear-out, sectioning framing in place, the everything tool.
- Plumbers — cast iron DWV, copper, PVC; the one-handed compact for under-sink and rough-in work.
- Electricians — conduit, strut, flush trims, opening up old-work boxes.
- Fire & rescue — vehicle extrication and forcible entry, on break-resistant bi-metal 10–14 TPI blades. When a tool is trusted to cut people out of cars, that's a reputation data point.
- Landscapers and yard DIYers — pruning with a dedicated ~5 TPI blade, limbs up to roughly 6 inches, lighter and safer in hand than a chainsaw for occasional work.
A tool five trades reach for daily will handle anything your house throws at it. That's the case for buying a good one once.
The signature job: cutting out a rotted deck board, nails and all
This is the job that sells the tool, so here's exactly how it goes — no nail-pulling, no prying the whole frame apart:
- Fit a bi-metal demolition blade (6–10 TPI) rated for nail-embedded wood. This step is the whole trick — a wood-only blade dies at the first nail.
- Plunge in mid-span between the joists: rest the shoe on the board, tip the saw so the blade clears the wood, squeeze the trigger slow, and rock the blade down into the rot until it's through.
- Cross-cut the board just inside each joist, keeping the shoe pressed to the work so the saw doesn't beat itself against the board.
- Slide the blade flat alongside the joist and cut the nails or screws flush — bi-metal eats them. The freed section lifts right out.
- Pry out the stubs, check the joist for rot, screw down the new board. Gloves and glasses the whole time — the blade is hot enough to brand you when you swap it.
Don't ruin it — getting your money's worth
- Let the shoe ride the work. Press the shoe against the material and let it take the vibration — a floating saw beats itself and your wrists, and snaps blades.
- Match the blade to the material. TPI is the whole game: 6–10 for demo wood, 14–18 for metal, ~5 for pruning. Wrong blade reads as "weak saw" every time.
- Slow down on metal. Low speed, steady pressure, let the teeth cut — full trigger on cast iron just glazes the blade. Expect to burn a blade per cut on old 4-inch pipe; that's normal, not failure.
- Don't side-load or pry with the blade. It cuts on the pull stroke; levering the saw sideways bends blades and wears the clamp.
- Wipe the clamp after wet work. Wet cast-iron cuts are what seized the old-gen clamps — a ten-second wipe keeps the mechanism free.
- Big pack for demo days. A full-size saw on a small battery sags; feed it the biggest pack you own when the work is real.
A word on Milwaukee — the name that became a verb
It's worth knowing why one brand's model name means the whole category. Milwaukee engineers built the first portable electric reciprocating saw in 1951 and called it the Sawzall — a tool good enough that it was inducted into JLC's tool Hall of Fame, and a name good enough that the whole trade adopted it for every saw of the type. Forty years later, in 1991, Milwaukee added the counterbalanced Super Sawzall — the direct ancestor of the vibration-control argument this whole page is built on. When a brand name turns into a verb on job sites for 75 years, you're not paying for marketing; you're paying for the company that defined the tool and still makes the version the trades carry.
FAQ
Is a Sawzall the same thing as a reciprocating saw?
Yes — "Sawzall" is Milwaukee's trademarked name for the reciprocating saw it invented in 1951, and the name went generic the way Kleenex did. Every brand makes a reciprocating saw; only Milwaukee makes a Sawzall. When someone says "grab the Sawzall," they mean any recip saw within reach.
Is a reciprocating saw worth it for a homeowner?
Yes, once you own a drill and a circular saw. It's the demolition and "get me out of trouble" tool: rotted deck boards, fence posts, pipes, pruning. Nothing else cuts nail-embedded wood in place. Buy it bare-tool on whatever battery platform you already own.
Can a reciprocating saw cut tree branches?
Yes — with a dedicated pruning blade (around 5 TPI). It handles limbs up to roughly 6 inches and is lighter, quieter, and safer to handle than a chainsaw for occasional yard work. Past that size, or for all-day cutting, you want the chainsaw.
Will it cut through wood with nails in it?
That's the whole point of the tool. Fit a bi-metal or carbide demolition blade rated for nail-embedded wood and cut straight through — no pulling nails first. This is why remodelers reach for a recip saw over a circular saw on tear-out work.
What does orbital action do?
Orbital action swings the blade in a slight ellipse instead of straight back-and-forth, so it rips through wood dramatically faster but rougher. Switch it off for metal — steel and cast iron want a straight stroke. It's the feature that separates premium demo saws from basic ones.
Should I buy a one-handed or full-size reciprocating saw?
Full-size first — demolition, decks, and pruning all want two hands and a longer stroke. The one-handed compact (Hackzall-style) is the second buy: overhead cuts, under-sink pipe, tight mechanical spaces. Plumbers and electricians often carry both; homeowners rarely need the compact first.
What blades do I actually need?
Three cover almost everything: a bi-metal demolition blade (6–10 TPI) for wood with nails, a metal blade (14–18 TPI) for pipe and rod, and a pruning blade (~5 TPI) for the yard. The blade matters more than the saw — cheap stock blades make good saws feel weak.
Can I cut cast iron pipe with a reciprocating saw?
Yes, with a carbide or cobalt-tooth demolition blade around 14 TPI — plan on burning up a blade per cut on old 4-inch pipe. Pros often rough it with an angle grinder and finish with the recip saw where sparks are dangerous. Patience, low speed, steady pressure.
The bottom line
One saw, one answer: the Milwaukee M18 FUEL Sawzall 2821-20, bare tool — the trades' everyday carry, with the clamp that survives wet demo and the weight your arms can live with. Go Ryobi PBLRS02B if you're on ONE+ batteries and demo is a few weekends a year; go Super Sawzall 2722-20 when the job is measured in rooms. If you're on DeWalt, the DCS386B is your answer and don't let anyone platform-shame you. Whatever you buy: get it from an authorized seller, and put the first savings into the three-blade kit — the blade matters more than the saw.
