I think the beautiful craftmanship is a given with many high cost modern razors. But I've learned in the short time that I've been DE shaving that "The better or best shave" is totally YMMV!Admire the Rocnels, but for their craftsmanship. If anyone can prove that they can actually shave better than acknowledged classics like the New SC, many would be very impressed.
And psychology probably plays a role as well in how good of a shave that "expensive" razor gives.
Using my short list of high quality razors, I can attest to this because of the example I gave today on another thread.
My Karve CB brass shaves just as good as my ATT Windsor! (no psychology involved!) They just both work as good as the other.
One is a $200 razor and the other was less than $60!
I believe that something like a Rocnel would probably be a purchase that would showcase pride of ownership above the shave quality.
Now, that the owner would believe that or not is a different story, LOL!!
