Review on 100 Count | Parker Safety Razor Double Edge Blades | Premium Platinum Stainless Steel with PTFE, Tungsten & Chromium Coating | Smooth & Comfortable Shaves by Sonja Garcia

First of all, these baddies are instantly SHARP. Only my razor is sharper, which needs to be sharpened before each use. I shave both my face and head and that's the equivalent of shaving twice a day. For me, shaving is 30 minutes of personal time. I have used the Astra and Derby Premium and while both are great blades these are the BEST yet. I've been wet shaving since I was 15 (I'm 63 now) and it's always been a quest for good blades. I look at the sharpness and also at the duration. I've been shaving my head and face for 3 days and still haven't shaved. I daresay I'll be working with the original blade for another 1 or 2 days before I have to change it. So if you only shave 6-10 shaves before your shift depending on how thick and coarse your beard is. NO disposable blades with handles can top this! Not even six blades. I gave the knife to my wife for her legs and she is more than happy with it. Get them and a quality dual bladed pen and you'll be done. My A Gillette Flare Tip Super Speed pen was inherited from my father, as was my razor, so I have no recommendations. Parker makes a handle for their DE blades for you to check out. But take the Blades Parker. You will not regret it!
