My first was Personna Lab. I then got another 100 of those that I haven't touched, around 300 Polsiver SI blades, maybe 90 Personna Med Preps, some assorted blades, and a few vintage ones. I think I'm good for a little while.
Haven't bought a 100 pack yet...Still have some of my first blade sampler, and was lucky enough to get PIF'ed another blade sample. I just recently ordered another 10 different brands to try... maybe my next order will be for a 100 pack!
Wilkinson Sword not my favourite blade but a good blade that works well in all my razors and pretty cheap. A good everyday blade that gives great shaves. IMHO
Astra SP were the first. I still love them, but have found a different blade that works even better for me - Rapira Platinum Lux. Waiting for my order of 300 to arrive this week. Gotta stock up for the shavepocalypse.
There is little in life that is not worth over doing. Voskhods were my second 100. Together, Feathers and Voskhods are my entire inventory.
Derby was the first 100 pack I ordered. I switched razors around the time that I ordered and/or my technique changed, because I didn't like them when they came in. I ended up swapping them out for some Personna Reds. Since then I've stuck with the Personna line and Astra SPs.
Gillette Silver Blue, Voskhod and Rapira were all ordered in 100 blade groups. Why did I need enough for 4+ years? No one knows, least of all me.
Shark Super Chrome was my first two years ago, but it only had 50 blades in it. I have not been using them exclusively, so I still have two 5-packs left. I just received 30 Astra SPs.
Derby - as a noob, it made sense to order a 100pack for only $9.50 Definitely ready to try some new blades - I'll probably end up giving away a bunch of the Derbys - seems like it'd be a good newbie PIF.
A set of NOS Max Herder blades. Vintage, nice to use and re-hone-able in my Allegro De blade sharpener. They should last a while that way!
Derby. PIF'd a bunch but still have several packs. They work great with my Fatboy and I still enjoy them.
