Replacement Cartridges, 8pcs Wilkinson Sword Quattro Titanium Sensitive

I have been using the Wilkinson Sword interchangeable knuckle duster blades for some time now. I haven't found any drawbacks for myself. I used to use Gillette Venus before, but I have no desire to go back to it. The sharpening is excellent, the blades don't dull quickly, it doesn't cause irritation, there is a risk of cuts as I believe with any razor, but here the ergonomics are good. The price/quality ratio is excellent.
