All of the Old-world, still operational, razor brands all make nothing but high-end razors: Dovo, Thiers-Issard, Heribert Wacker, Maestro Livi. Fancy details, such as blade decoration and luxurious scale materials boost the price, but they don't make a razor less practical, only more beautiful, depending on taste of course. Some vendors sell NOS (new old stock) razors made by companies that stopped production at some point in history. Depending on what you can find, Revisor, Henckels (Friodur), Filharmonica, Heljestrand, Puma, Boker, Dorko, Bartmann, Dubbl' Duck are all of indisputable quality. Some of them are nearly impossible to find as NOS. There are many other brands, that you can buy in used stated and have restored by one of the craftsmen you can contact though this website. Wade & Butcher is a roaring name that jumps to mind, but there are countless others.

Based upon your heavy beard, I think you might benefit from buying one of the heavier grinds: 6/8 - quarter hollow grind, or 7/8 -full hollow grind. Those razors add a bit of inertia to the shave, allowing it for a steadier course through your wire bush.

Maybe the best way to approach this, is to borrow a few different types of razors and see what you like best, before making a final purchase. I'm pretty sure there are enough fine gentlemen present on this forum, willing to help a straight shaving barber out on that one. (that includes myself)

Best regards,
Bart.
