Query: Great Blades!

I recently switched to wet shaving and had been using the ONLY double-edged blades I could find at my local wally world. It was still a huge step up from my old Mach 3 but I decided to go all out and get some genuine Merkur blades to see if I was missing out. I was missing out.These blades are head & shoulders over the lame ones you'll get at your local discount store. I've cut myself twice while shaving with these blades, but only because I was trying to rush myself. The blade seems sharper and it seems to hold it's edge much longer than the ones I was using previously. I've definitely noticed less tugging on the hairs.Aside from the blade upgrade, the next best thing I did was buying grapeseed oil to replace my expensive art of shaving pre-shave, and buying some poraso shaving cream to replace my expensive art of shaving cream.I've been shaving for almost 15 years and I'm just NOW getting the best (and cheapest) shaves of my life. GET THESE!
