Good results from a first run - so, similar performance, different feel on the face and the DuraSharp feels to be the better finished. Good work!
I mentioned above that one consideration might be for the intended market - Barbershop or home shaver. When I've compared the likes of an "Economy" blade intended for Barbershop use against the "Super Stainless" intended for the homeshaver, I've felt the difference on the first shave but by the second and certainly by the third, they are feeling very much the same. I'm thinking SuperMax Economy Stainless (burgundy pack) vs Super Stainless (green/yellow pack) or Wilkinson Sword Economie (yellow writing on the pack) vs Super Stainless (regular pack). I think the extra finishing on the packs intended for non-professional use is better and very evident in the first shave.
... so, it will be very interesting to know what you think of the second and third shaves.
I'm putting together the comments that we had from Connaught that these are the same blade with what we read from the supposed Gillette insider who said that Gillette only make three blades. Well, this all might well be true - the Classic and the DuraSharp might well be absolutely the same blade, but the grind, finish and coating makes ALL the difference. Double-stropped for a smoother (domestic) finish and double-coated for a super-glide.
Consider also the two blades that I showed above - same blade, but are they for difference geographical markets or for different intentions. I think the New Steel is better finished and intended for home shavers, while the burgundy pack is clearly picking up on the Barbershop favourite "kala" (Black) blade stylings and I would guess intended more for professional use. The writing on the blade is clearly better on the New Steel, more rough and ready on the "New Treet".
Let's see how you find the second and third shaves. Will they come together in terms of performance and feel?
