I received a Treet Platinum blade along with a few others as a little thankyou for placing an order from yourshaving.com. To be honest, I wasn't really expecting much from it but decided to try it in a Muhle r89 Twist. Very strange sensation as it felt as though there was no blade loaded in the razor at all....then, surprise as it gave me a really good and more than acceptable shave. No cuts, nicks or irritation at all. I had 5 very nice shaves from the blade and would certainly use Treet's again.
