1st shave with a '67 SS black handle, 2nd with '64 Slim Adj, 3rd shave, same blade with the new Sentry. Amazingly sharp. The Permasharp & Nacet have been my best blades to this point, but the REX is the new pinnacle of Sharp & Smooth !! Shouldnt have expected anything else from Mr. Matt !

These blades are sharp and smooth; they are one of my new favorite blades! They are top quality. Thank you Rex! I will be ordering more.

I've tried 30 different blades, and The Rex is #3 out of those blades that I would use on the regular. The other two are Feather and Erbe. I'd put the Rex right in the middle between those two blades. Great quality from blade to blade, and they work great in my Leaf Twig. Will definitely purchase more in the future.

These blades are "the one" for me in my Rex Konsul. They're sharp and smooth, delivering consistently great shaves with hardly ever a weeper. As if the above wasn't great enough, they're also quite durable, with each one lasting weeks and enough shaves that I lose count. I ordered the 100 pack 3.5 months ago, and it was love at first shave. I've been trying to use up some of the other blades in my collection during that time, but I keep longing for these, and when I plop one back in it's just as great as I remembered. After these 3.5 months I'm still only on blade #3, so it's going to be a long time before I've used them all.
