PHILIPS OneBlade X2 360 Replacement Dual‑Way Blade QP420.50 — Dual‑Sided Cartridge, Rounded Tips

PHILIPS OneBlade X2 360 Dual‑Way Blade (QP420.50) is a replacement, double‑sided cutting head engineered to restore precise trimming, edging and shaving performance on compatible Philips OneBlade handles.

If your OneBlade has lost its keen edge or doesn't glide as smoothly, the X2 360 Dual‑Way replacement blade brings back fast, even cutting and neat edge control. This cartridge is designed for the QP420.50 specification and fits all Philips OneBlade models that accept standard replacement heads, providing the same dual‑direction convenience and rounded tips for comfortable contact with skin.

How does the dual‑way blade improve my shaving and trimming routine?

The dual‑way design lets you cut in both directions without flipping the whole unit, which speeds up grooming and helps maintain uniform results. The slim profile and precise teeth work together to follow facial contours so you can tackle stubble, trim beards, or outline clean edges.

• Double‑sided cutting edges for forward and backward strokes
• Thin blade profile for closer contact with skin and contours
• Rounded tips to reduce irritation while edging
• Quick clip‑on cartridge replacement in seconds
