The DE blade arena is a big amorphous blob where it's difficult to see the wood for the trees sometimes (or that's the way it feels to me anyway). Although dependent on other factors, not least the razor in hand, it might help to get a handle on the best performing blades if members could nominate their favourite three desert island DE blades. Let's stick to currently available blades rather than NOS exotica. Maybe we could put the results into somekinda graph.
I genuinely think it takes a couple of years to fully get to grip with the whole DE experience. Especially blades/razor combos. Anyway my two penn'orth:
The search for the best performing blade is futile, like the best performing brush.
Ya can however decide what you like best after trying a few.
My bulk stash now consists of Polsilver SI, GSB and Rapira Swedish Super Steel.
For sharp smooth blades Polsilver and GSB are up there as good as any.
The Rapira SS are a very good smooth mid range blade.
My favourite list is:
1) Kai Stainless Steel (difficult to find but I discovered a new online store recently)
2) Feather stainless steel
3) Personna Med Prep
