Almost every bad purchase of replacement blades has the same reason: two series from the same manufacturer have similar names but different blade mounts. This guide shows where to find the model designation and which blade belongs to which handle.
First: Where can I find my model?
- Manual razors (Gillette Fusion5, Venus): The series name is usually on the handle itself, otherwise on the packaging of the blades you have purchased previously.
- Philips OneBlade: The model number starts with "QP", for example, QP2530. You can find it on the handpiece or on the original packaging.
- Electric toothbrush (Oral-B): The model name is on the handpiece or on the packaging.
Once you have the designation, you can enter it directly on the product pages in the "Does this fit my razor?" field – or use the device finder on the home page.
Gillette Fusion5
Fits: Handles from the Gillette Fusion5 ProGlide series. We do not have separate confirmation for special and battery-operated variants – in case of doubt, compare the mount of your old blade with the product photos or ask us.
Does not fit: Gillette Mach3 and Gillette Sensor. The mount is different.
The easiest distinction: A Fusion5 cartridge has five blades on the front, a Mach3 cartridge has three. If you still have the old blade, just count them.

Shaver heads for electric shavers
For electric shavers, it depends on the exact series – which spare parts fit which Braun and Philips devices is explained in our guides Braun shaver head and foil and Philips shaver heads.

And if my model is not listed?
Then we do not have confirmation for this device – that does not necessarily mean it won't fit. In that case, a look at the product photos helps: Compare the mount of your old blade with the one shown. Or send us a quick message via the contact form; we will tell you what we know – and what we don't.
