Default Sharpening new router bits?

Greetings: I have been reading this for some time, but have not contributed. I will introduce myself soon.
A tool sale and repair guy just told me that the US government limits how sharp router bits can be when manufactured, and that “high-end” woodworkers have new bits sharpened before use. After 30 years in woodworking I have never heard of this.
Please advise - is this idea real or imaginary?

Thanks for any info

I have never heard of that before and have never sharpened a bit before I used it.

Sounds pretty bizarre. Any reputable tool sharpening service, or for that matter, tool manufacturer should be able to give an explicit answer to that claim. E-mail Amana or Whiteside.

I've never heard of this. If you read through some of the bit makers "About Us" profiles on their websites they'll tell about their sharpening process which usually means at least the equivalent of 600 grit if they have any pride in what they are producing. Finer grits mean more sharpening time which combined with carbide quality equates to better quality which is what separates one maker from another. If there was a law that prevented them from making their bits as sharp as they could be the best makers would be telling you that.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Don't buy anything from that guy. He doesn't know what he's talking about.
Bits are sharpened on the same types of machines that make them. And by the way they are manufactured, there's really no way to limit how sharp they are.
The only bits that may not be really sharp when new are really cheap bits, where the edges are ground with course grinding wheels, and have a noticeably rough edge.

Myth from an unreliable source, who probably heard it from a guy who heard it from a guy...

It sounds like so many YouTube garbage entries and videos. An occasional few strokes with a diamond dresser on the REAR of the Carbide keeps my bits sharp.

This should be moved to the "Jokes" category!
