chipper knives - best ones?

[Frans]

I've always bought my knives from the dealer.
But I have a feeling I can buy knives that are superior to and exceed manufacturer specs.
Is this true?
Who do you recommend?
Price is not an issue I am seeking knives that far exceed manufacturer specs.

Most of the blades that you do get aren't made by the OEM. I think most are sure sharp? Usually the OEM does a decent job on picking a good blade, the problem is they kill you on price. Zenith makes a good blade too. If you can get them aftermarket from either one of these companies, you probably won't see a difference on performance but a difference on price.
