I think he may have misunderstood the assignment. But I wouldn't be surprised if he was forced to bin the feather after 3 shaves. Feather longevity is the worst of any quality blade I've ever used IMO.Is that a new blade, meaning you only got three shaves from your first one. If so why? I thought your initial blade was doing fine.
Or have I completely misunderstood (something I do on a regular basis )?
