What Razor Blades Fit My Gillette Handle? (Full Compatibility Chart)

Finding the right replacement razor blade for your Gillette handle can sometimes be confusing. With several product ranges available, including Mach3, Fusion5, SkinGuard and Labs, it is important to know which cartridges are compatible with your existing razor.
This guide explains which Gillette razor blades fit each handle, highlights the differences between the major shaving systems, and includes a handy compatibility chart to make choosing your next replacement blades simple.
Why Compatibility Matters
Not every Gillette razor cartridge fits every Gillette handle. Each shaving system uses its own connection mechanism, meaning an incompatible blade simply won't attach securely.
Using the correct replacement cartridge ensures:
- A safe and secure fit
- Smooth shaving performance
- Proper pivoting movement
- Maximum shaving comfort
- Longer handle lifespan
Checking compatibility before purchasing helps you avoid unnecessary returns and wasted money.
Gillette Razor Systems Explained
Gillette has introduced several shaving systems over the years. Although many look similar, each uses a different cartridge design.
The most common Gillette razor systems include:
- Mach3
- Mach3 Turbo
- Fusion5
- ProGlide
- ProShield
- SkinGuard Sensitive
- Gillette Labs with Exfoliating Bar
- Gillette Labs Heated Razor
Knowing which family your razor belongs to makes finding compatible cartridges much easier.

Which Blades Fit Mach3 Handles?
Mach3 handles are designed exclusively for the Mach3 family of cartridges.
Compatible blades include:
- Mach3
- Mach3 Turbo
- Mach3 Start
These cartridges all share the same attachment mechanism, allowing users to switch between them without replacing the handle.
However, Fusion5 and Gillette Labs cartridges will not fit Mach3 handles.
Which Blades Fit Fusion5 Handles?
Fusion5 handles offer greater flexibility because they are compatible with several cartridge types.
Fusion-compatible cartridges include:
- Fusion5
- ProGlide
- ProShield
- SkinGuard Sensitive
This cross-compatibility allows users to experiment with different cartridge technologies while keeping the same handle.
Are ProGlide and ProShield Compatible?
Yes. One of the biggest advantages of the Fusion platform is cartridge interchangeability.
If you own a Fusion5, ProGlide or ProShield handle, you can generally use:
- Fusion5 cartridges
- ProGlide cartridges
- ProShield cartridges
- SkinGuard cartridges
This gives users greater flexibility when selecting blades based on comfort or budget.
Do Gillette Labs Blades Fit Other Handles?
No. Gillette Labs uses a completely different cartridge connection.
Gillette Labs cartridges are only compatible with:
- Gillette Labs Handle
- Gillette Heated Razor (specific Heated cartridges)
Likewise, Labs handles cannot use Mach3 or Fusion5 cartridges.
How Do I Identify My Gillette Handle?
If you are unsure which razor you own, there are several easy ways to identify it.
Look for:
- The product name printed on the handle
- The number of blades on the cartridge
- The handle shape and design
- Original packaging if available
If your razor has three blades, it is likely part of the Mach3 family. If it has five blades, it is most likely from the Fusion5 range.
Should You Upgrade Your Razor Handle?
If your current handle is still in good condition, replacing only the cartridges is usually the most economical option.
However, upgrading your handle may be worthwhile if you want:
- Improved grip
- Better lubrication technology
- Precision trimming features
- Enhanced shaving comfort
- Access to newer blade systems
Choosing the right system depends on your skin type, beard thickness and personal shaving preferences.
Tips for Choosing the Right Replacement Blades
Before purchasing replacement cartridges, keep these points in mind:
- Check your razor model carefully.
- Buy genuine Gillette cartridges.
- Replace blades regularly for optimal performance.
- Store cartridges in a dry environment.
- Purchase from trusted UK retailers.
Using authentic replacement blades helps maintain shaving comfort and ensures the best possible performance.
Common Compatibility Mistakes
Many first-time buyers accidentally purchase incompatible cartridges. The most common mistakes include:
- Buying Fusion5 blades for a Mach3 handle
- Assuming all Gillette cartridges are interchangeable
- Purchasing Gillette Labs cartridges for Fusion handles
- Confusing Mach3 Turbo with Fusion5
A quick compatibility check can prevent these issues and save both time and money.
