Nice razor, congrats! My experience with the edge of my NOS Barbas Duras was the same - I was amazed at how sharp it was right out of the sealed plastic. Totally unexpected surprise.
The other thing I noted is that the Barbas Duras is not just a #14 with a rubber tang grip, as I expected. They seem to be different razors but both excellent. The grind on the Barbas Duras feels thinner to me, and it handles and shaves a bit differently. Mine lacks the typical smile of the #14 Doble Temple, is more evenly balanced, and is more aggressive. My #14 Doble Temple feels thicker, blade-heavier, and has a more forgiving-feeling edge.
The scales are different too. The Barbas Duras scales are harder and shiny, the Doble Temple scales are softer and dull (but with great vintage automobile/guitar colors). Both are admittedly cheap-feeling, but the Barbas Duras seems less so. I love the rubber tang grip too.
The shave from the #14 Doble Temple is unique, I haven't felt anything exactly like it in terms of how it handles and feels against the skin. Big, heavy, sharp, friendly. Like a more refined W&B chopper. The Barbas Duras reminds me a little bit of a really good Friodur, both in terms of how well it handles for it's large size, and for it's edge. Big, but precise, streamlined in it's handling, and just wickedly sharp and efficient.
Love them both. Those Spaniards got it right. :y
