I like a good etch, it’s just one of those cool little aesthetic things. They go away with use and if you polish them off, so I’d rather they do them than not, all things being equal.
BUT… it must be said, from an economic perspective, put me in the “less etches” camp. let’s say I am not sure if I love a knife or not. It’s highly sought after and acquiring it cost me a notable amount of effort, angst, and not a little treasure. Now, if it didn’t have an etch, I’d be able to judiciously carry it for a couple of days, and not really worry. A quick polish and I’d be back to 99% condition. With an etch, the blade is more or less permanently stained by any patina, since flitzing will remove the etch as readily as the patina. This is a great thing for “old school retail,” the etch is like a guarantee the knife is unused. But it’s annoying in today’s market when we’re all mostly buying and trying used knives. Less etches would probably mean buyers could try the knife a bit and not feel like they were throwing away lots of money, which would probably mean more lightly used knives changing hands, and better prices for everyone, in the long run.
