I think that the main value of this sample pack is to discover what level of sharpness you prefer. When I started wet shaving I just bought a box of Feather blades not knowing that there are significant sharpness differences between blades. This pack has excellent representations of three categories, let’s say low, medium, and high levels of sharpness.
Low: Merkur, Derby, Dorco.
Medium: Astra, Gillette 7 o’clock, Personna Israeli.
High: Bic Platinum, Feather, Crystal Israeli.
I won’t bore you with my experience since yours will be different. But the exercise of trying different blades to find what you like is well worth doing. Also, you end up with about 70 blades. There’s only blade in this lineup (Bic) that I won’t go back to. So it’s at least a year’s worth of blades.
My favorite? Surprisingly to myself I’d have to say the Crystal Israeli with a super slick soap and good technique when I have time to go slow. The Bic drew blood too many times to be forgiven.
