After using the Sharp Titanium blade in a very mild TTO razor, I shaved this morning using another Sharp Titanium blade in my Karve brass with a D plate. That is significantly more aggressive/efficient than my TTO. I found the Karve D plate and Sharp Titanium to be an excellent match. I got a much better shave than I did using the mild razor. I did experience a tiny bit of feedback when I applied witch hazel after the shave, so it was not a zero irritation shave, but it was still excellent. I consider the Sharp Titanium blades to be a great value: sharp, smooth, and inexpensive.
