Had my first properly enjoyable shave today (as in not overthinking technique, angle etc), and without immediately apparent irritation on my neck.
Hot Shower
EJ DE86
Feather blade (1st shave)
The Traditional Shaving Company Best Badger
TOBS Sandalwood Cream
TOBS Sandalwood Aftershave Balm
After trying a Derby and a Gillette Yellow prior to this shave with the feather, I think the key to avoiding irritation on my neck is definitely a sharper blade and fewer passes. Makes me think I might prefer a more aggressive razor. Well, I have a Gillette Old Type on the way, so I might give that a try...
