Trimming and Shaving
- Prepare your skin: You can use the OneBlade on dry or wet skin, with or without shaving foam/gel. For best results and comfort, wet your face and apply shaving foam or gel.

- Power on: Press the power button to turn on the OneBlade.
- Glide the OneBlade: Glide the OneBlade over your face in the direction of your hair growth. For a closer shave, use short, quick strokes against the grain. The blade is designed to follow the contours of your face.

- Power off: Press the power button again to turn off the OneBlade when finished.
