The best safety razor is the one whose handle suits how you shave, because every razor below takes the same standard double-edge blade (the Leaf Two takes it snapped in half), and the blade is the part you keep buying. A three-piece such as the EcoRoots has no moving parts; a butterfly head like the ZWS Essentials changes blades with one twist; the Rockwell 6S lets you set how much blade meets the skin, starting on the mild setting Rockwell recommends for beginners; and the Leaf Two’s pivoting head is the nearest thing to a cartridge razor. At September 2026 prices, a year of double-edge blades costs $2 to $20 at three shaves a week, and a year of cartridges $21 to $91, depending on the brand and how often you change them.
If a cartridge or disposable razor is already in the shower, use it and its refills up first: the savings and the waste reduction come from the refills you stop buying, not from owning a new handle. After that, a metal razor lasts as long as you look after it, and the only thing it throws away is a small steel blade, which belongs in a sealed tin headed for a scrap-metal drop-off or a mail-back program, never loose in the recycling bin.

Which Handle Type Fits
Every safety razor clamps one blade between a cap and a base plate. The handle type decides how the blade goes in, how many parts can wear, and how small the razor packs:
- Three-piece: the handle unscrews and the head comes apart into cap and plate. Nothing moves, and it breaks down smallest for travel.
- Two-piece: the head stays on the handle, and turning the knob at the base releases the cap.
- Butterfly: twisting the base of the handle opens two doors over the plate, so the blade goes in without taking anything apart; the hinge and twist mechanism are the extra parts.
- Adjustable: changes the gap between blade and plate, which sets how much blade reaches the skin. The Rockwell 6S does it by swapping plates; other adjustables, including Rockwell’s own T2, use a dial.
- Pivoting: the head tilts to follow the skin the way a cartridge does. Leaf’s holds two half-blades.

What the razor is made of matters most if you have a nickel allergy. DermNet NZ, a dermatologist-written reference, lists razors among the personal items that can contain nickel and cause dermatitis in allergic people, and says stainless steel does not usually cause dermatitis unless it is nickel-plated. Two razors here are sold as stainless steel: the Rockwell 6S, in 316L stainless, and the ZWS Essentials. The Merkur 34C is chrome-plated brass and zinc, and EcoRoots lists zinc alloy and stainless steel without saying which part is which or what gives the rose-gold finish its color. Leaf doesn’t name the metal of the Leaf Two.
Three-Piece: EcoRoots
EcoRoots’ razor is a classic three-piece: by EcoRoots’ own description, the handle unscrews and the head separates into a cap and a plate with the blade between them. It is listed as zinc alloy and stainless steel and sells for $39.50 in rose gold or black with five stainless-steel blades, and EcoRoots suggests a new blade after four to six uses (Sept 2026).
Most of its running cost is blades. EcoRoots’ own are $4.99 for ten, about 50 cents each, but the razor takes any standard double-edge blade, so a 100-pack at about 9 cents a blade fits it too. The product page doesn’t state a warranty.
Butterfly: ZWS Essentials
The ZWS Essentials razor that EarthHero sells is a butterfly in polished stainless steel, with ten blades in the box and two handle lengths: 3.5 inches for $27.99 or 4.75 inches for $35.99 (Sept 2026).
Which length depends on what you shave: a face needs little reach, but legs and underarms need more, and our guide to safety razors for legs and underarms compares handle lengths and head mildness for that shave.
Two-Piece: Merkur 34C
The Merkur 34C, from the Solingen, Germany maker, is a two-piece with a short, heavy handle: shopmerkur.com, which sells Merkur razors in the US, lists a brass handle and a die-cast zinc head, both chrome-plated, at 78 grams. Merkur’s Amazon listing says the closed-comb head minimizes nicks. It was $52.00 on Amazon and $55.00 at shopmerkur.com (Sept 2026).
Adjustable: Rockwell 6S
The Rockwell 6S sets the blade gap, the space between blade edge and plate, with three two-sided base plates numbered 1 to 6, and Rockwell publishes the gaps: 0.20 mm on setting 1 up to 0.79 mm on setting 6, a measurement no other maker here gives. The razor is 316L stainless steel, costs $120.00 from Rockwell or on Amazon, and carries a lifetime warranty (Sept 2026).
Rockwell recommends starting on setting 1 to get the feel of the razor and describes settings 4 to 6 as meant for thick, coarse hair, so the same razor can start mild and move up. Rockwell also sells each 6S part separately (handle $25, top cap $20, each plate $25) and says it supplies replacement parts free, shipping aside, after accidental damage. The cheaper Rockwell 2C ($40, in a chrome finish) has settings 1 and 3 only.
Pivoting Head: Leaf Two
If the give of a cartridge head is what you would miss, the Leaf Two keeps it. Its head pivots on a spring and holds two individually guarded single-edge blades, loaded with a magnetic assist, and Leaf says it feels natural even to someone new to safety razors. The razor alone is $109 from Leaf; the kit with a stand, 50 blades, a blade tin and a grip sleeve was $149 from Leaf and on Amazon (Sept 2026).
Leaf says a load lasts 8 to 12 shaves on average, and the razor takes Leaf’s own blades or a standard double-edge blade snapped in half inside its wrapper, so there is no proprietary refill. The pivot also means springs and magnets that a fixed head doesn’t have, and Leaf’s standard warranty on them runs one year, against lifetime coverage on the Rockwell 6S. On its own site, Leaf offers a 30-day return.
Blade Cost per Year vs Cartridges
The table assumes three shaves a week, 156 a year, the rate behind Harry’s own 21-shave figure for its Plus cartridge. The first cost column changes the blade or cartridge every six shaves, the middle of the American Academy of Dermatology’s five to seven; the second takes each maker’s own claim for how long its blade lasts.
| Refill | Pack (Sept 2026) | Each | A year, changed every 6 shaves | A year at the maker’s stated life |
|---|---|---|---|---|
| Astra Platinum double-edge blades (Amazon) | $8.88 for 100 | $0.09 | $2.31 | No claim |
| Rockwell double-edge blades | $18.00 for 100 | $0.18 | $4.68 | No claim |
| EcoRoots double-edge blades | $4.99 for 10 | $0.50 | $12.97 | $12.97–$19.46 (4–6 uses) |
| Leaf single-edge blades, two per load | $14.95 for 50 | $0.30 | $15.55 | $7.77–$11.66 (8–12 shaves a load) |
| Harry’s Original cartridges | $17.00 for 8 | $2.13 | $55.25 | $20.72 (16 shaves) |
| Harry’s Plus cartridges | $25.00 for 8 | $3.13 | $81.25 | $23.21 (up to 21 shaves) |
| Gillette Fusion5 cartridges (Amazon) | $27.99 for 8 | $3.50 | $90.97 | $30.32 (up to 18 shaves) |
Even on the cartridge makers’ longest estimates, Harry’s 16 to 21 shaves a cartridge and Gillette’s up to 18 on its Amazon listing, a year of cartridges costs $21 to $30. On the same schedule as a blade, it costs $55 to $91. The blade brand moves the number more than the razor does: EcoRoots’ own blades cost about five and a half times as much per blade as an Astra Platinum 100-pack, which was $8.88 on Amazon (Sept 2026) and fits every razor on this page, the Leaf Two included once each blade is snapped. Buy the Astra Platinum 100-pack at Amazon.
Payback depends on the razor’s price. Leaving shipping aside, the $27.99 ZWS Essentials with Astra blades costs about $28 a year less than Fusion5 cartridges at Gillette’s own estimate, so it pays for itself in about a year. The $120 Rockwell 6S with Rockwell’s $18 100-pack takes close to five years on the same comparison, which is why the warranty and spare parts matter more on an expensive razor.
The Learning Curve and Nicks
The American Academy of Dermatology’s shaving tips apply to any razor: shave in the direction the hair grows, rinse after each swipe, shave lightly to prevent nicks, and change the blade after 5 to 7 shaves. Its razor-bump advice adds short strokes and never going over an area more than twice. What a safety razor adds is the angle: EcoRoots says to hold it at about 20 to 30 degrees, with no pressure, and let the weight of the razor do the work.
The makers’ answer for the first weeks is a milder setup: Rockwell’s setting 1, a closed-comb head like the Merkur’s, or the Leaf Two’s pivot, which Leaf says keeps the blades in contact without angle corrections. Lather matters as well: the academy’s tips start with wet skin and a shaving cream or gel, and our comparison of low-waste shaving soaps and creams covers what to use.
Flying With a Safety Razor
Pack the handle and the blades apart. The TSA allows a safety razor in carry-on bags only without its blade, which has to come out before the checkpoint because officers can’t remove it, and razor blades not in a cartridge are banned from carry-ons; both can go in checked bags, with the blades sheathed or securely wrapped. Leaf’s loose single-edge blades fall under the same rule. For a carry-on-only trip, take the empty handle and buy a pack of double-edge blades after you land, or pack a disposable razor you already own, which the TSA allows in carry-ons. If travel is part of the decision, a three-piece packs smallest.
Keep the Razor You Already Own
An old double-edge razor in a drawer, a parent’s or a thrift-shop find, takes the same standard blade as the razors above. Clean it, check that the cap sits evenly over a new blade, and it may be the only razor you need. The same goes for a safety razor bought years ago and set aside after a few nicks: fresh blades and the technique above cost less than a new handle.
Once the disposable or cartridge razor you already have and its refills are used up, TerraCycle’s Gillette Recycling Program takes all brands of blades, razors and plastic razor packaging, free at public drop-off points or by mail if you pay the shipping, though TerraCycle notes that enrollment limits may apply.
Where Used Blades Go
Used blades go into a sealed metal container: a slotted blade bank, a mint tin, or a can taped shut. At three shaves a week and a change every six shaves, that is about 26 blades a year, and Leaf says most people take years to fill a tin. What to do with it when it is full depends on where you live, and the makers disagree. Leaf says most curbside programs aren’t equipped for blades and points to local scrap-metal yards; Rockwell tells buyers of its blade tin to put the full tin in the recycling. Burbank, California’s recycling guide says razor blades should never go in the recycling bin because they endanger workers: blades can go in the trash cart taped or in a sealed container, and larger amounts, consolidated in a lidded metal can, can be dropped at the city’s recycle center as scrap metal. The same guide treats a metal razor handle as scrap metal.
Two razor makers take blades back by mail. Albatross’s take-back program accepts double- and single-edge blades of any brand, by mail or at drop-off points, and the company says the steel is melted with new steel into its Take Back Ware utensil sets. Leaf takes a full tin, or an old Leaf handle, by mail if you can’t find a scrap-metal facility nearby. The TerraCycle program above also accepts blades.
Frequently Asked Questions
Do safety razors cause more cuts?
The makers expect a learning period. EcoRoots says to give yourself time to get used to a new razor, and Rockwell recommends starting the 6S on setting 1, its mildest. The American Academy of Dermatology’s advice applies to any razor: shave in the direction the hair grows, in short strokes, with a sharp blade, and lightly to prevent nicks.
How often should you change a safety razor blade?
The American Academy of Dermatology says after 5 to 7 shaves. The makers’ own figures run from 4 to 6 uses (EcoRoots) to 8 to 12 shaves for each load of the Leaf Two’s two blades. At three shaves a week and a change every six shaves, that is about 26 blades a year, or $2.31 from a 100-pack of Astra blades at September 2026 prices.
Can you use a safety razor on your legs?
Yes. The blades and technique are the same; what changes is reach, so a longer handle helps, such as the 4.75-inch ZWS Essentials. Leaf says the Leaf Two’s pivoting head adjusts to the contours of the face, body and head. Our guide to the safety razor for women covers handle length and head mildness for legs and underarms.
How do you dispose of used razor blades?
Keep them in a sealed metal tin, never loose in the recycling or the trash. When the tin is full, check your local rules: some cities, Burbank among them, take a lidded metal can of blades as scrap metal at a drop-off site rather than curbside. Albatross and Leaf take blades back by mail, and TerraCycle’s Gillette Recycling Program accepts blades of any brand at public drop-off points, or by mail if you pay the shipping.
Is a safety razor better for razor bumps?
The American Academy of Dermatology’s razor-bump advice says a single-blade razor or an electric razor is often recommended, and a double-edge safety razor holds a single blade (the Leaf Two takes one or two). The rest of that advice is technique: a sharp blade, changed after 5 to 7 shaves; short strokes in the direction the hair grows; never over the same area more than twice; and no shaving closely or pressing hard.
