Changing your razor blades seems simple… until the cartridge does not fit the handle, the blades start pulling after just the second use, or the cost of each shave becomes hard to justify. For both men and women, the right choice depends above all on compatibility, head design and how often you shave — not simply on the number of blades shown on the packaging.
By Joybuy Product Recommendation Officer, with a selection based on practical, verifiable criteria.
Razor cartridges are not universal. A Gillette Mach3 refill will not fit a Fusion5 handle, while Venus blades use their own attachment system. The same applies to Wilkinson: the Quattro, Hydro and Hydro Silk models belong to separate ranges.
Before placing your order, note the exact reference printed on the handle or on the old cartridge. A simple mention of “Gillette” or “Wilkinson Sword” is not enough to confirm compatibility.
Five blades will not necessarily suit everyone better. A wide head can be less manoeuvrable in hard-to-reach areas, while a safety razor with double-edged blades requires greater precision and a short learning curve.
Comfort also depends on the spacing between the blades, the flexibility of the head, the lubricating strip and how the razor is used.
A pack of 24 refills may seem particularly good value, provided the handle is compatible and you use that range regularly. Conversely, a smaller pack may be preferable if you want to try a new system before buying in larger quantities.
Claims such as “up to 15 or 20 shaves” are still estimates. Actual lifespan varies according to hair density, the area shaved, the pressure applied and how thoroughly the razor is rinsed.
This is the first thing to check. Here are some examples from our selection:
If you are unsure, compare the shape of the attachment system and the full reference, then check the information provided on the product page.
Three-blade models generally offer a more compact head and a lighter sensation as they pass over the skin. Four- or five-blade razors provide multiple contact points and sometimes include a precision blade at the back for edging.
Also look out for the following features:
These features provide information about the product’s design, but do not guarantee the same experience for every skin type.
The number of refills should match how quickly you use them. A pack of 6 or 8 cartridges may be enough for regular use, while a pack of 12, 15 or 24 blades means you do not have to place orders as often.
Replace a cartridge when it becomes less comfortable, starts pulling on the hair, shows signs of wear or is damaged. Rinse it thoroughly after every use and allow it to dry in a clean, dry place.

Stainless steel, a stated triple coating and compatibility with standard double-edged safety razors.
We have brought together a complete, real-time updated selection of products that meet these demanding criteria and European safety standards.
To make your replacement blades last longer:
A blade that is damaged, rusty or has become uncomfortable to use should be replaced. If irritation occurs, stop using it and avoid shaving skin that is already irritated or damaged.
Start by identifying the exact range: Mach3, Fusion5, Sensor, Venus, Quattro, Hydro, Bulldog or Monsieur Barbier. The brand name alone is not enough. Check the compatibility information on the product page and compare the shape of the cartridge with your old model.
It depends entirely on how you use it. Some references claim up to 15 or 20 shaves, but a cartridge should mainly be replaced as soon as the glide or comfort decreases. On models with integrated gel, wear on the lubricating bar can also provide a useful indication.
They can reduce the amount of plastic used, and their standard format allows you to choose from a wide range of references. However, the actual cost depends on the price of the handle, how often you replace the blade and how confident you are with the technique. A safety razor should be used with light pressure and a consistent angle.
