I very regularly hone razors for other people. Often those are almost new razors. Mostly Dovo's, occasionally Thiers Issards, rarely Wackers, and twice so far a Maestro Livi.
Test shaving them all, there is something I peculiarly like about the edges I can put on the TI's, but that's a personal preference. Yet I do not own a TI, because I am not willing to spend that amount of money on tool of which I already own more than I use. (about a dozen). That too is a personal preference.

I also find it hard to buy vintage razors, for a price that I am willing to spend, in a condition that puts them in the same class as a new one. I am not talking about a bit of corrosion, because that can be fixed in most cases. I am talking about the amount of steel that is missing from most vintage razors, vanished through years of careful honing jobs.
Those razors still shave very well, but there just is something extra in a high quality razor, still in the prime of its life, without being honed down to the belly of the grind. You can find that in NOS vintage razors, or you can buy new ones. It comes with a price. In the case of new ones that price is justified by labor costs, social protection (I am glad to live in the EU) and the rules of a free market. Otherwise you can buy Gold Dollar razors. Allegedly they're nice too. Ebay sellers of NOS razors don't have production costs, they're just lucky to cash in on the inflation of an object that was produced several decades ago.

I disagree with the notion that today's production is of lesser quality than what we call vintage. Philharmonica ceased production and a few years later, prices have gone up and people are talking in superlatives about them. I don't think so. They're as good as when they were still in production. The same thing counts for Puma, Dorko and all the other famous brands. Why do it always seem the "best" brands that went out of production?

Best regards,
Bart.
