There is great variety in knives today. But for me, there are only a few types (traditional or modern) that really hold my interest anymore. I started out in the '70s with Schrade, Buck, etc., then moved on to Vic and Wenger SAKs. IMO, those old knives still hold up today. I became interested in 'modern' knives in the late '90s. But my own preferences nowadays are: Victorinox, CRK and Spyderco.
I still like the Vic SAK steel, as well as steels like VG-10, S35VN, H1, etc. I don't prefer some super steel that holds an edge for a longer time but is hard to resharpen. Why, when some new super steel comes out, do yesterday's 'super steels' suddenly suck? They don't; it's only an OCD type of opinion that believes so. I once heard a guy saying that he 'has to' buy a new cell phone every couple weeks to a month, because he knows that by the time he buys it, its technology is already obsolete, and he always 'needs' the latest technology. Even though he admitted he never came close to using all the phones' features. Same type of obsession.
I kinda shake my head when people have videos on youtube showing expensive tactical-style knives opening cans with only minimal damage to the tip and edge, as if that's an impressive feat. All I do is use the can opener on my below-$30 SAK with zero tip or edge damage to my knife, and a much cleaner cut, too.
