A razor for your body is two purchases pretending to be one. The handle is bought once. The blades are bought again and again, for as long as you keep shaving. Most of what makes one razor better than another for you is decided by the second purchase, and it is the part a shelf label does not show you.
This page is for someone buying a manual razor for legs, underarms or bikini line, and who wants to know which format suits which job and what it costs to keep using. If you would rather not hold a blade against your skin, best electric shaver for women and bikini trimmers cover the powered options.
Four razors follow, mapped to the areas that decide the choice: a cartridge system for legs and underarms, a second cartridge system with the cheapest refills, a disposable for the bikini line and travel, and a bulk box that wins on cost per shave.
The four picks at a glance
Prices here are the listing prices shown on the cards below, checked in November 2026. They move. The arithmetic is the part worth keeping, because you can run the same sum again on the day you buy.
| Pick | Format | What is in the pack | Pack price ÷ units | Best for |
|---|---|---|---|---|
| Gillette Venus Extra Smooth Sensitive | Cartridge, metal handle | 1 handle + 2 refills | $14.97 ÷ 2 = $7.49 per refill cartridge | Legs and underarms, if you want a metal handle and a holder |
| Billie | Cartridge, magnetic holder | 1 handle + 4 refills | $14.99 ÷ 4 = $3.75 per refill cartridge | Lowest cost per refill, for shaving often |
| BIC Soleil 3 Sensitive | Disposable, triple blade | 5 razors | $8.29 ÷ 5 = $1.66 per razor | Bikini line, travel and short-term use |
| BIC Silky Touch | Disposable, two-blade | 40 razors | $10.69 ÷ 40 = $0.27 per razor | The cheapest per shave, in bulk |
One method across all four rows: the pack price divided by the number of units you actually shave with. On the two cartridge razors that means refill cartridges only — the handle is included in the price but not counted as a cartridge, which is why that figure falls as soon as you are buying refills alone. On the two disposables every razor is a unit, and it never falls.
The picks in detail
Gillette Venus Extra Smooth Sensitive — the metal handle, at the higher cost per cartridge
This is the pick to start with for legs and underarms. It arrives as a reusable handle with a metal body, two refills and a shower holder, and the listing positions it for sensitive skin. A metal handle puts more weight in your hand than a plastic one, which helps when you are working by feel around a knee, an ankle or an underarm, and the holder means the razor hangs dry instead of lying in water.
The trade-off is arithmetic: two refills is a short runway, and at the listing price it works out to roughly twice the per-refill cost of the Billie below. You are paying for the handle once and for a starter set of two, and the cost that matters starts with the next refill pack. “Sensitive” in the product name is a positioning label, not a promise. A razor like this may give sensitive skin a more comfortable starting point, but technique and how often you change the blade do at least as much.
Billie — the lowest cost per cartridge in the first pack
Billie ships one handle, four refills and a magnetic holder, and works out to the cheapest cartridge of the two refillable systems here. The magnetic holder is a small thing that turns out to be useful: a razor that hangs dry instead of sitting in water keeps its strip and blade edge in better condition between shaves.
The catch is that four cartridges is what the starter box gives you, and refills bought on their own are a separate pack at a separate price. That pack’s price divided by its cartridge count is the figure to compare with the $3.75 above before you commit, because a low opening price with expensive refills is the most common way a razor stops being good value.
BIC Soleil 3 Sensitive — the disposable for bikini line and travel
Five triple-blade disposables with a comfort shield and a moisture strip, in assorted handle colors. At a dollar and change each, this is the pick for the areas where you want a fresh blade and no storage problem: a trip, a gym bag, or a bikini line you shave less often than your legs.
What you give up is the handle. A disposable is not designed to have its head replaced, so when the strip goes and the blade drags, the whole razor goes in the bin. That is fine at this price and annoying if you were hoping to keep one handle for years, and it is the reason a five-pack is a sensible size to try rather than a box of forty.
BIC Silky Touch — the cheapest per shave, if you want forty of them
Two blades, travel covers and forty razors in one box. At roughly a quarter per razor this is the lowest cost per shave on this page by a wide margin, and for legs it is a perfectly workable answer if your skin is not easily upset.
Two things to be honest about. Forty razors is a commitment to storage and to a format you cannot adjust: no refills, no different head, no second chance if the blade angle does not suit you. And the place a cheap razor usually shows its limits is the shin bone and the ankle, where a flatter, less forgiving head catches on an uneven surface.
What a razor really costs after you buy the handle
Three numbers decide the cost of shaving: the price of the pack, how many blades or razors are in it, and how many shaves you get from each. You can check the first two in the shop. Nobody can tell you the third in advance, because it depends on your hair and how often you shave, so treat any confident shaves-per-blade figure as a guess about you rather than a fact about the razor.
So compare the first two and treat the third as the variable you control. Divide the pack price by the units inside it:
- Gillette Venus Extra Smooth Sensitive: two refills for $14.97 is $7.49 a refill, in a first purchase that includes the handle.
- Billie: four refills for $14.99 is $3.75 a refill, in a first purchase that includes the handle.
- BIC Soleil 3 Sensitive: five razors for $8.29 is $1.66 a razor.
- BIC Silky Touch: forty razors for $10.69 is $0.27 a razor.
Then run the sum again with the refill pack you would actually rebuy. That second figure is the one that decides whether a cartridge system is cheaper than a box of disposables over a year, and it is the figure the handle price hides. A cartridge system front-loads the handle and then sells you blades; a disposable spreads a handle across every unit you throw away.
The limit on all of this is that unit cost is not the same as cost per comfortable shave. A blade that drags gets replaced early, and a razor that nicks you costs more in patience than in money. If you shave your legs twice a week, a cheap disposable is genuinely the rational buy. If you shave daily over a large area, the arithmetic usually moves toward whichever refill pack is cheapest per cartridge, whatever the handle cost.
Which format fits which body area
Legs
The largest area, so unit cost dominates and blade life matters more than handle quality. Start with the Venus if you want the metal handle and the shower holder, or the Billie if the cheaper refill matters more than the handle. If you would rather not maintain a handle at all, the Silky Touch box is the cost-first answer. For the technique that keeps the shin and ankle intact, see how to shave your legs.
Underarms
Small, curved, and the area where most people cut themselves, because the skin is loose and you are working by feel. A razor you can steer beats a razor with more blades, which is the argument for the Venus and its metal handle here. If you would rather use a fresh blade than keep one clean, the five-pack of Soleil 3 is the low-commitment option for this area. Technique first: shaving your armpits.
Bikini line
The smallest and least forgiving area on this list, and the one where a fresh blade is worth more than a good handle. A disposable you can keep fresh and discard avoids the problem of a cartridge that has already dulled on your legs. If the skin there reacts badly to any blade, the honest answer may be a trimmer rather than a closer shave: shaving your bikini line covers technique and bikini trimmers covers the powered alternative.
Sensitive skin
Sensitive skin responds more to blade condition, pressure and preparation than to which of these four razors you pick, and the design details matter more than the format: razors for women with sensitive skin covers seven gentle options and what makes each one gentler.
Two related problems are worth separating from the razor choice. If your hair curls back into the skin, the fix is technique and blade angle, not a different handle: shaving curly hair. If what bothers you is the speckled look after shaving rather than the shave itself, that is strawberry legs.
What a cheaper razor costs you
Three things go wrong with a razor you have kept too long or bought too cheaply. The strip wears smooth and stops gliding, so you press harder to compensate. The blade edge corrodes if it lives in a puddle on the shower floor, which is why a holder that hangs it dry is worth more than it looks. And a fixed, unsupported head catches on the shin bone and the ankle far more readily than it does on the flat of the calf.
Sometimes none of that matters. If you shave a small area once a week, or you are buying for a trip and will throw the razor away at the airport, the cheapest disposable is the correct answer and the durability arguments do not apply. The mistake is paying cartridge prices for a blade you never change, or disposable prices for a shave you expect to be comfortable every day.
If a blade is not working for you
A manual razor is not the only route, and for some people it is the wrong one. If you want a shave without a blade against the skin, best electric shaver for women explains how to choose by body area. If the problem is ingrown hairs or a bikini line that reacts to every razor, bikini trimmers and electric razors for pubic hair cover the powered alternatives. And if you want a cartridge set with a lubricating strip, the JOY cartridge set has its own review.
Before you buy
- Check what is actually in the box. One handle and two refills is not the same purchase as four refills, and the headline price looks similar.
- Price the refill pack, not the starter pack. Divide its price by the number of cartridges and compare that with the disposable you were considering.
- Decide the body area first. Legs reward unit cost; bikini and underarms reward a fresh blade you can steer.
- Do not pay extra for a handle you will not keep. A magnetic or hanging holder is the feature that actually protects the blade between shaves.
- Buy the smaller pack if you are unsure. Blade condition and technique decide more than the model, and a five-pack tells you that cheaply.
The short version: pick the format for the area you shave most, then do the division on the refill pack before you commit. Everything else about a razor is a preference you can change later for the price of one pack.
