That Rex Sentry slant ^^^ is a bank account drainer and it has a really chunky head.
@BelfastBlade what blade(s) are you planning to use. I ask because for my first slant shave I tried to play it safe by using what is considered to be a mediocre blade for sharpness and I did not have a great experience. I then tried two blades(Gillette Nacet and SharpEdge), which are generally accepted to be in the "sharp" category that gave me a significantly improved experience. So my point is, as with all razors blade choice is important.
Happy slanted shaves with your new German 37!
Newver used a slant, but REX just sent out E-mail Blast about New Slant that you can preorder. Posted info already.
