An unprecedented 6th day with the Razorpit treated Wilkinson DE blade. Still going strong and producing a smooth, nick-free, comfortable shave with no sign of irritation (as confirmed by the alum block). No incremental stubble either – just a clean , close, comfortable shave, BBS smooth.
How far can this thing go?

So you just push the razor up the strip, blade in, fully tightened, polishing one side of the blade? (I finally figured out that the curved thing was just a stand for when you not using the RazorPit and razor.)
That’s it, nothing simpler. Give it 3-4 strokes.
