So, I've been reading and exchanging knowledge on razors with some other straight razor shavers.

We've so far discussed on the ground, and it seems that modern-production razors are not as ground (or "thin") as some vintage razors. I've been told that even modern day (i.e. current production) "singing" TIs and DOVOs are actually closer to a "half hollow" and that the "extra hollow" or "singing hollow" titles are only marketing.

Is this true?

I don't have a lot of knowledge on straight razors because I've never experienced shaving with a vintage razor. I've only had modern day DOVOs and Bokers, and I'd like to know if the vintage extra hollow stuff are actually thinner blades than modern day DOVOs, Bokers, TIs, etc.

I'd also like to know which is the thinnest razor in production right now? TI Evide Sonnant? DOVO Prima Klang?

Thanks for any info,
Kind regards,
Mike
