I don’t buy knives from Woot! out of solidarity with my brothers and sisters in New York. I have several Kershaw knives and find that depending on where you buy them you stand a chance of getting a fake.
Many fakes replace the bronze washers, like this one has, with nylon washers. Buyer beware.
As to this knife, I like mine but I do know of one instance where the spring broke. Here’s a link.
