Really nice to see there are bona fide practical 'users' amongst the multitude of 'voyeurs' and 'wannabees' that seek to spend serious scratch on 'a' knife in the mistaken belief that their's is somehow gonna way be better, than something proven over time, by virtue of an exorbitant price tag and/or some fancy sales pitch. My now 25 year-used kitchen knives were NOS (from the 1950s I think) from when Sabatier, France (would have been even nicer, at the time, if these were Solingen or Sheffield-made) was consolidating/amalgamating their operations and couldn't sell a carbon steel nor wood handled knife anymore. Give credit to the invention of automatic electric dishwashers (which immediately ruin wood and steel knives) and fashion-conscious women for making this happen. Their loss was my gain! These lovely knives have been a real joy and are going into the ground with me unless one of my heirs develops a similar appreciation of good steel.
You can get lifetime's use from blades as long as you don't use electric sharpeners or other rude/crude grinding methods. Quality carbon steel is still the best bar none. (I say this because a foundling $5-10 'real-steel' knife can easily be made as sharp or sharper, and stay that way, than any Yuppie-fashionable stainless job that requires the equivalent of a mortgage payment in order to purchase, display and make sharp at home)
