PHILIPS ORIGINAL BLADE ONE BLADE

• This is a replacement blade for the Philips “OneBlade” hybrid trimmer & shaver system (which trims, edges & shaves). 

• Model/Variant: QP210/50 (also QP210/51, QP220/51) among others. For example, the QP220/51 pack includes 2 replaceable blades. 

• Compatibility: Designed to fit all OneBlade handles. 

• Longevity: Philips states each blade “lasts up to 4 months*” under typical use (based on 2 full shaves per week) before needing replacement. 

• Features: The OneBlade system is designed with a cutter moving at high speed (200× per second), dual-protection (blade never directly touches skin), capable of dry/wet use. 

 Key Benefits

• Optimised for trimming, edging & shaving: Because the OneBlade system is designed for all three tasks, the replacement blade allows you to maintain optimum performance for these tasks.

• Reduced skin-irritation risk: The blade system is designed such that it “cuts hair, not skin” and uses glide coating and rounded tips for comfort. 

• Easy maintenance & cost efficiency: Rather than replacing the whole trimmer/razor handle, you just swap the blade when it slows down/dulls — more economical and simpler.

• Universal fit for OneBlade handles: Makes upgrading/maintenance easier across the OneBlade ecosystem.

• Wet & dry use compatibility: You can use the OneBlade system (and thus the blade) in the shower or with foam, offering convenience. 

 How to Use & Replace the Blade

Here’s how you’d typically install and use a new OneBlade replacement blade:

1. Turn off the handle: Ensure your OneBlade handle is switched off and unplugged/charging as necessary.

2. Remove the old blade:

   • If your model has a slide-switch blade release: push the release switch while holding the blade on both sides, lift off. 

   • If no release switch: press both edges of the blade and lift it off the handle.

3. Attach the new blade:

   • Remove the replacement blade from packaging (be careful—edges are sharp).

   • Align and press both edges of the blade into the handle until it clicks securely. 

   • Start using: With the new blade in place, you can trim, edge or shave as usual with your OneBlade device. For best results: use long smooth strokes, against hair growth direction if shaving. 

4. Clean & maintain: After use, rinse if wet/dry compatible, remove hair debris, dry out. Regular cleaning helps blade stay efficient.

5. Replace again when dull: As the manufacturer suggests: typically after about 4 months of typical use (or earlier if you notice decreasing performance).
