Blackbird is more efficient than Tr3?I bought the seconds from Split seven a while ago. I must say that I have absolutely no regrets. It doesn't feel like the blackbird to me. It is smoother and affords a less shallow shaving angle so steeper shavers can enjoy it as well.
The TR3 is very efficient, delivering a BBS effortlessly and doesn't feel aggressive. The overall blade exposure is not the highest, so the shave longevity is slightly shorter than the blackbird OC.
Overall, I found myself loving the TR3 a whole lot. I almost do not use the TR2 at all, always reaching for the TR3.
