All About Pocket Knives

On the vintage 4353 I read in a knife book that it was rare to
see one etched. I checked Mel Brewsters book, he did not say
anything about this. Any opinions on this? I would like to
know what is correct.

Thanks

All the R4353's I see in original catalogs, advertisments, etc do have a blade etch. I would assume that pattern would not be less likely to receive an etch as the others in the Bullet line.
Now if we're talking about today, then I would say yes, its rare to see one that is still etched.
