4F 9.5mm
This is the blade that started it all. So impressive I invested in other sizes. Have a look at the videos I took to track the trial 4F’s progress.
All new blades have their spring tension reset, oiled and test cut.

Clip off before a bath. Week 26 sample blade still going strong. Sharpened only once.
