The coating will protect against corrosion but regarding the edge this is something I expect to sharpen weekly which I don’t mind at all at this price point.
Regarding the sharpness..mine came nice and sharp and cut paper better than I expected. And..well about 6 hours ago I got a case of butter fingers and dropped it. Caught it with my foot and for my carelessness I got 3 stitches out of the deal. It has no issue cutting through Asics running shoes. Embarrassing to admit, but there it is.
Only 5 days in but until I want to shell out for a $100ish EDC this seems like a great value.
