Review on Premium Black DERBY TOKAI Swedish Steel 100 Half Razor Blades by Teresa Olson

I wanted to find the best half blade for my Leaf and Twig razors. I ordered the Shark brand, Barber razor blade (Japanese stainless steel) and these Derby Tokai blades. Barber razor blades did not fit Leaf or Twig razors. Hit one. The shark is slightly thicker but less sharp when fresh. The Leaf razor lasts for about 3 fairly comfortable shaves. By the fourth shave, I consider changing the blade before I begin. Derby Tokai blades are thinner and sharper. They also ensure a noticeably closer shave and easily last two to three days longer than Shark blades. I usually shave with these blades for five to six days. My clear favourites.
