Wilkinson Sword are my go-to blade (coarse grey beard). For me, they last twice as long as some of the cheaper blades and IMHO are better than Feather on two counts - these are smooth from the first stroke, whereas feather seem to take a few strokes to settle in, and these have just the right amount of wax to hold the blade (vs feather, which have two big blobs).
100 packs of these have been like hen's teeth since covid (apparently still are), but still good value in the 5 packs.
Super-fast delivery, as always.
