Loading a blade into a safety razor is pretty logical, but lets explain it in 4 simple steps. It goes without saying that the blade is sharper than a serpent's tooth so go easy.
Hold the head of the razor between your index finger and your thumb. Twist the handle counter-clockwise to separate.
Separate the razor head from the base plate.
Insert the new blade - hold it by the shorter, blunt edges and locate on the lugs.
Put the head back together and screw the handle back on, but don't over tighten.
We learnt to shave by watching our Dads right? So lets have a little re-cap.
1. Hold the razor at an angle of 30 degrees to your face.
2. Don't apply any pressure to the razor, let its weight do the work.
3. Move the razor in short, even strokes.
4. To avoid razor rash don't be tempted to scrape upwards ... off you go then.
