The blade is the easy part. The saw is the hygiene problem, and nobody tells you that before you buy. A reciprocating saw has a blade clamp, a pivoting shoe and a gap where the plunger enters the housing, and every one of those traps bone dust and marrow. You cannot dismantle it, you cannot put it through a dishwasher, and you cannot see inside it. That is precisely why commercial butchers use band saws built with removable, washable guides and stainless housings, and it is the reason a reciprocating saw is a field and shop tool rather than a kitchen one.
That has a practical consequence rather than being a counsel of despair: if you are going to saw bone for food, keep a saw for it and use it for nothing else. A saw that has been through pressure-treated lumber, exhaust pipe and drywall is not a food tool, and no amount of wiping the blade changes what is inside the housing.
On the blade itself, the specification runs against instinct. Bone wants a coarse tooth, roughly 5 to 10 TPI. It feels like dense material that should want a fine metal-cutting blade, and a fine blade is exactly wrong — the gullets between the teeth fill with bone dust and marrow within a few strokes, the blade stops cutting, and you start generating heat instead of chips. Big teeth with deep gullets clear the swarf and keep cutting.
Material is the second decision and it is a genuine trade. Bimetal blades cut faster and survive being flexed or twisted in a cut, but ordinary bimetal is not stainless and will rust between uses. Stainless blades sold for butchery clean up properly, tolerate sanitiser without pitting, and dull sooner. For anything you intend to reuse across seasons, stainless wins; for a single big job, bimetal cuts better.
Length is the underrated one. A 9 or 12 inch blade lets you take a straight pass through a large bone with the saw body clear of the work. A 6 inch blade has you pressing the shoe into whatever you are cutting, at an angle, which is how blades bend and cuts go ragged.
One last thing worth saying plainly: for portioning cooked or raw meat at home, a good bone cleaver or a hand bone saw is usually the better tool. A reciprocating saw earns its place on large carcass work, frozen bone and shop jobs — not on a kitchen counter.

The picks, in detail
Diablo Pruning and Bone Blade, 9 inch
The most-used blade for this job outside a professional butchery, and the logic is sound: green wood and bone both want a large aggressive tooth with room to clear waste. Bimetal construction survives hitting dense bone at a bad angle, and 9 inches is enough to take a straight pass through most of what you will meet. Not stainless, so dry and oil it or treat it as consumable.
- Coarse pitch for green wood and bone
- Bimetal construction
- 9 and 12 inch lengths
- Universal shank
- Cuts bone fast without packing up
- Survives twisting and flexing in a cut
- Cheap enough to dedicate several
- Not stainless — rusts if stored damp
- Coarse teeth grab on thin or brittle bone
- Leaves a rough surface and bone chips
Stainless Steel Butchery Reciprocating Blade
The right choice for anything you will clean, sanitise and use again. Stainless tolerates a bleach or quaternary sanitiser soak without pitting, which ordinary bimetal does not, and it will not leave rust marks on the next carcass after a week in a damp shed. It dulls faster and cuts a little slower — that is the price of being cleanable, and for repeat food work it is worth paying.
- Stainless steel construction
- Coarse bone pitch
- Tolerates sanitiser without pitting
- Reusable across seasons
- Actually cleanable and sanitisable
- No rust in storage or in a cooler
- Sensible for repeated food use
- Dulls noticeably faster than bimetal
- Costs more per blade
- Slower through heavy frozen bone
Diablo Carbide-Tipped Reciprocating Blade
Bone is abrasive, and abrasion is what carbide is for. A carbide-tipped blade holds its edge through many times more bone than steel, which turns a blade-per-carcass habit into a blade-per-season one. It is the sensible economy if you process real volume. Carbide teeth chip rather than blunt if the blade is twisted, so keep the cut straight.
- Carbide-tipped teeth
- Long edge life in abrasive material
- Bimetal body
- Multiple lengths
- Stays sharp through far more bone than steel
- Cleaner cut with less chipping
- Economical at volume
- Several times the price per blade
- Teeth chip if the blade twists in the cut
- Wasteful for occasional use
Milwaukee Torch or Ax Blade, Coarse Pitch
Bought for the body rather than the teeth. Milwaukee’s heavier-gauge blades resist the flex and twist that occurs when you are cutting through a joint at an awkward angle with one hand steadying the work — which is the moment cheap blades snap. The coarse nail-embedded-wood patterns handle bone well. Sold in bulk packs, which makes dedicating blades to food work affordable.
- Heavy-gauge body
- Coarse tooth patterns
- Multiple lengths
- Bulk packs available
- Body strength survives awkward angles
- Bulk packs make dedication practical
- Stocked everywhere
- Not stainless
- Labelled for construction, so pitch needs checking
- More blade than an occasional user needs
12 Inch Coarse Blade
Length is the specification that most improves a difficult cut and the one people underestimate. Twelve inches lets you split a large pelvis or take a sternum in one confident pass with the saw body well clear of the carcass, which produces a straighter cut and keeps the tool out of the mess. It flexes at full extension, so it wants a firm grip and a steady feed.
- 12 inch length
- Coarse pruning or bone pitch
- Bimetal body
- Universal shank
- Reaches across large bone in one pass
- Keeps the saw body clear of the work
- Inexpensive
- Flexes noticeably at full extension
- Unwieldy in confined spaces
- Needs clearance some saws do not have
Dedicated Cordless Reciprocating Saw
Buying a second saw sounds extravagant until you consider what is inside the first one. A cheap dedicated saw kept only for food work solves the contamination problem that no cleaning routine solves, and a compact one-handed model is easier to control on a carcass than a full-size demolition saw. Take two batteries; cold weather and dense bone both eat runtime.
- Compact one-handed body
- Common battery platforms
- Variable speed trigger
- Tool-free blade change
- Separating food and shop tools is the only real fix for the housing problem
- Controllable in awkward positions
- Tool-free blade change matters with wet hands
- A second tool to buy and store
- Battery runtime falls sharply in the cold
- Still not fully cleanable inside
Hand Bone Saw with Replaceable Blades
For a couple of cuts, this is genuinely the better tool. A hand saw has no motor housing to harbour anything, it comes apart for cleaning in a sink, and it throws a fraction of the bone dust a powered blade does. Slower, obviously, which for the two or three bone cuts a home butchery job actually requires is not a real cost. Stainless frames and blades are standard.
- Stainless frame with replaceable blades
- Coarse bone tooth pitch
- Dismantles for cleaning
- No power source
- Genuinely cleanable, unlike any powered saw
- Throws far less bone dust
- Works anywhere
- Hard physical work on a large pelvis
- Blades dull quickly on bone
- Awkward without a second pair of hands
Heavy Bone Cleaver
The traditional tool, and the correct answer for most home jobs on this list. A heavy cleaver splits ribs, portions shanks and cuts poultry with one controlled stroke, cleans completely in thirty seconds, and produces no dust at all. It demands technique and a proper block, and it does not replace a saw for splitting a whole carcass — but for anything that fits on a counter it is faster, cleaner and safer.
- Thick heavy blade with a strong spine
- Full tang construction on good ones
- Stainless or carbon steel
- Requires a solid chopping block
- Completely cleanable
- No bone dust at all
- Faster than a saw for counter-sized work
- Requires technique and a proper block
- Cannot split a whole carcass
- A dull or badly aimed cleaver is dangerous
Food-Safe Sanitiser and Long-Cuff Gloves
The part of this job that protects you rather than the meat. Long-cuff nitrile gloves keep your forearms out of it and stop the saw slipping in a greasy hand, and a proper food-contact sanitiser is what the blade and any work surface need afterwards. Bone dust travels further than you expect — plan on wiping down a wider area than the one you cut on.
- Long-cuff nitrile gloves
- Food-contact quaternary or chlorine sanitiser
- Dedicated bucket or spray bottle
- Disposable rather than reused
- Cheap relative to what it prevents
- Long cuffs keep forearms clean and improve grip
- Proper sanitiser rather than improvised bleach ratios
- Nitrile tears on sharp bone edges — take spares
- Sanitiser pits non-stainless blades
- Contact times need respecting, not guessing
Fine Metal-Cutting Blade (the wrong choice)
Listed because it is the blade most people reach for, and it is the single most common mistake in this job. A 14 to 24 TPI metal blade looks like the right tool for something hard and dense. In bone the small gullets pack with dust and marrow within a few strokes, cutting stops, and the blade starts burning through friction instead — which smells exactly as bad as it sounds and glazes the bone surface.
- 14–24 TPI fine pitch
- Bimetal, intended for steel and pipe
- Short gullets between teeth
- Cheap and widely stocked
- Correct for its actual purpose, which is metal
- Cheap
- Fine finish on the material it is meant for
- Gullets pack with bone dust within a few strokes
- Generates heat rather than chips
- Glazes and burns the cut surface
Buying tips
- Dedicate a saw to food work and use it for nothing else. The blade clamp, shoe and plunger gap all trap bone dust, and none of them can be dismantled or properly cleaned.
- Buy coarse — roughly 5 to 10 TPI. A fine metal-cutting blade packs with bone dust and marrow in a few strokes and then generates heat instead of cutting.
- Choose stainless if you will reuse the blade, bimetal if you want the fastest cut. Stainless tolerates sanitiser without pitting; bimetal cuts better and rusts.
- Go long. A 9 or 12 inch blade takes a straight pass with the saw body clear of the work, where a short blade forces the awkward angles that bend blades and ruin cuts.
- Use a cleaver for anything that fits on a block. It is faster, it produces no bone dust, and it cleans completely in half a minute.
- Chill or part-freeze what you are cutting. Bone cuts far more cleanly cold, and the mess stays where it is instead of spraying.
- Wipe down a wider area than you cut on. Bone dust from a powered blade travels well beyond the immediate work surface.
- Never cut towards your supporting hand, and clamp where you can. A reciprocating saw grabs when a coarse tooth catches, and bone is exactly the material that makes it grab.
