Picked up 200 of these in the violet pack(10s) on close out and was I surprised. As far as I can tell they are the same as the blue pack only difference being quantity per tuck. I have used Lord Super Stainless blades before (came w/L-625) and didn't remember how smoothly they shaved me. Sharp enough to do a complete 3-pass shave with excellent results! No weepers, nicks, cuts or after shave burn whatsoever. These are now my daily blade. I can get a whole weeks worth of shaves from one blade (probably more), but at these prices why bother! Find them, try them!
