These were the original starting supplies, I've ony used a few out of each brand. Maybe 20 Israelis, 15 Feathers and about 10 Derbys. I used to have way more Merkurs until I found these other better blades.
Hey, if I see a good deal on ebay, I'll stock up on some more, I can always pass them on when I die.
P.S. this list doesn't include a couple of hundred Gillette mach 3 and Sensor Excel blades that are rusting away for a long time now, although I do like the Sensor. I think it was probably Gillette's best multiblade razor ever.
