>>890644AliExpress had a ton of knockoff Chinese knives for dirt cheap but they will probably take a couple weeks for shipping.
KnifeCenter and BladeHQ are both reputable sites so you won't get a fake knife from them. And the country it was made in doesn't matter that much, quality control is the main issue. I have mentioned this before, you could have the exact same knife made in China and the US out of the same materials and the US one will cost 3x as much. The batch of 10,000 knives from the Chinese factory might have 100 that get to customers with some defect while the 10,000 made in the US have 10 bad knives go out because of QC. I would just buy the Chinese knife and hope I don't get one of the 100 defective knives. And even if I did get a bad one, if it is made by a good brand they will send you a new one anyway.
So just do your research on materials. There are lots of nice folders for <$40 that come from decent brands. Those Ontarios, the Esees, Kershaws, Gerbers, Byrds and whatever cheaper Spydercos, CRKT, Buck, and so on.
I try and look for shit on sale. There are always discontinued knives that you can get a steal on. I paid $17 with shipping included for the Kershaw with the orange handle and those were $40-$50 before the got disco'd and then the CRKT was around $25 and those were closer to $75.
There is also a dude on eBay who sells a ton of Kershaws for really cheap because they had a small scratch or other tiny imperfection and they couldn't sell them for full retail at REI or wherever.
