Hey, Ryan...get a TI for a great 2nd razor!
I guess it depends on the type of beard you have. If you have a heavy, wirey beard, then I would say a bigger blade will be better for you. I myself have a heavy beard. I started out with three 5/8 razors (Dovo "Special", TI "Evide Sonnant Extra", and a Hen & Rooster) and just received my SRP L/E 6/8 TI. In fact, I just shaved with it today. Is there a difference....Yes. The blade is a bit more heavy and it seemed to have no problem cutting down my somewhat heavy beard. Where I had trouble cutting with my 5/8s (the more course beard around my chin and mouth) I had no trouble today with the 6/8. I don't think I'll buy any more razors less than 6/8. Don't get me wrong, my 5/8s did, and still do, a fine job. The shave with the 6/8 just seemed a whole lot more effortless.
No silver in silver steel
Silver steel is the British term for what most Americans call O1 or W1 Drill Rod. It is a high carbon alloy with silicon, chromium and magnesium. Very hard stuff.
Of course, I could be wrong.
