Permasharp Super Double Edge Razor Blades - Pack of 100 Blades

After trying almost every other blade on the market I've settled on these as my best option. For a while I had used the Gillette Yellows, but found them generally too dull, bordering on painful if I had more than one day's growth to deal with. This was also the case with numerous cheaper options, including Derby, Shark, Astra and Wilkinson Sword.I find the Perma-Sharps to be sharper than all of those, but still smooth and comfortable. One blade lasts a working week for me, covering five shaves, with the first being several days worth of growth. In this routine the last two shaves can be a little harsh, but even if I use two blades a week I can still get a years worth of shaving for under £20 with these blades. So like the title says, a solid choice.
