All attachment systems listed

Gillette Mach3

3 blades

Gillette Mach3 · Gillette Mach3 Start · Gillette Mach3 Sensitive · Gillette Mach3 Turbo · Gillette Mach3 Turbo 3D

Confirmed on gillette.fr (official Mach3 Blades page, checked August 2026): “Gillette Mach3 razor blade refills can be used with all handles in the Mach3 range: Mach3, Mach3 Start, Mach3 Sensitive, Mach3 Turbo and Mach3 Turbo 3D.”

Gillette Fusion5 / ProGlide / ProShield / SkinGuard

5 blades

Gillette Fusion · Gillette Fusion5 · Gillette Fusion5 Power · Gillette Fusion5 ProGlide · Gillette Fusion5 ProGlide Power · Gillette Fusion5 ProShield · Gillette Fusion5 ProShield Chill · Gillette SkinGuard Sensitive · Gillette SkinGuard Sensitive Power

Confirmed on gillette.fr (official Fusion5 Blades page, checked August 2026): “Gillette Fusion5 razor blades are compatible with all Fusion5 razors as well as those in the PRO and SkinGuard Sensitive ranges: Fusion5, Fusion5 Power, ProGlide, ProGlide Power, ProShield, ProShield Chill, SkinGuard Sensitive and SkinGuard Sensitive Power.” Contrary to a common assumption (and an earlier version of this page), SkinGuard is therefore not a separate system — it shares the same clip as Fusion5/ProGlide/ProShield.

Gillette Venus (classic)

5 blades

Gillette Venus · Gillette Venus Extra Smooth · Gillette Venus Comfortglide · Gillette Venus Platinum

Classic Venus handles have shared the same cartridge clip across several generations.

Gillette Venus Swirl / Evo

5 blades

Gillette Venus Swirl · Gillette Venus Evo

Specific pivoting cartridge, not compatible with the classic Venus range.

Wilkinson Sword / Schick Hydro (whole range, 3 to 5 blades)

5 blades

Wilkinson Sword Hydro 3 · Wilkinson Sword Hydro 5 · Wilkinson Sword Hydro 5 Groomer · Wilkinson Sword Hydro 5 Ultimate · Wilkinson Sword Hydro Silk (women's) · Wilkinson Sword Hydro Trim & Shave · Wilkinson Sword Hydro Comfort Skin Reset

Confirmed on wilkinson-sword.fr (official Hydro 5 Ultimate Blades and Hydro 3 Blades pages, checked August 2026), word for word on both pages: “All Hydro razors are compatible with all Hydro blades.” This covers Hydro 3 (3 blades), Hydro 5 (5 blades, Regular/Sensitive/Ultimate), Hydro Silk, Hydro Trim & Shave and Hydro Comfort Skin Reset — contrary to an earlier version of this page which kept Hydro 3 separate out of caution. The blade count differs by variant (3 for Hydro 3, 5 for Hydro 5), but the handle attachment clip is the same across the whole range.

Wilkinson Sword Quattro

4 blades

Wilkinson Sword Quattro · Wilkinson Sword Quattro Titanium · Wilkinson Sword Quattro Essential

Confirmed on wilkinson-sword.fr (official Quattro Essential 4 Sensitive Blades page, checked August 2026): “These blades fit all Quattro razors.” A 4-blade system, separate from the Hydro range — cartridges are not interchangeable between the two.

Boni (Colruyt's own brand) — "classic razor" refill

3 blades

Boni 3-blade razor (Colruyt brand)

Closed store-brand system: these refills only fit their own handle, not Gillette or Wilkinson razors.

Very likely a closed system specific to the Boni razor range (Colruyt's own brand), sold with its own handle. No mention of cross-compatibility on the product page.

Carré Homme (E.Leclerc store brand) — 5 blades

5 blades

Carré Homme 5-blade razor (store brand)

Closed store-brand system: these refills only fit their own handle, not Gillette or Wilkinson razors.

A concrete example of the exact problem this tool aims to prevent: on e.leclerc, a customer reports buying 3-blade refills expecting them to fit their Carré Homme handle, which turned out not to be the case — proof that even within a single brand, ranges aren't necessarily interchangeable.

Carré Homme (E.Leclerc store brand) — 3 blades

3 blades

Carré Homme 3-blade razor (store brand)

Closed store-brand system: these refills only fit their own handle, not Gillette or Wilkinson razors.

E.Leclerc store brand, a closed system specific to its own handle range.
