I could buy that it starts out sharp, but how durable is it over time?
Every dinner table will have a piece of sandpaper, now.
Is it dishwasher safe?
Yeah, I almost asked that immediately but decided to read the article to see if it addressed it. It didn’t.
It did say it’s harder than regular wood, but it didn’t say how hard it is compared to steel, or even aluminum or copper.
It may only be good for a steak or two... i.e. good for an interesting news story or conversation piece in your dining room, but not “real world” practical.
