Fwiw, Amazon and other marketplace websites are just about the last place I'd buy a knife knowing what I know now from the time I've spent here.
Having said that, when I was fresh into knives, I bought a couple of CRKTs from Amazon and for the first time since that purchase, I recently bought a Mini CR from a 3rd party seller on the site (it's my only knife purchase from a non-authorized dealer). The
only reason I bought it on Amazon was because of the relatively recent goings-on at the Canada-US border.
At the time of the purchase, none of the (very few) Canadian Benchmade authorized dealers had the knife (or barely any of the new 2018 lineup - but I digress) in stock. As well, I didn't have enough faith in the CBSA to not seize the knife at the border had I decided to order the Mini CR from one of the many reputable US dealers down South. So that left me with this (again, at the time) seemingly lone seller on Amazon with some new Mini Crs that after an email, confirmed to me would be shipping from an origin within my country.
Given that I
really wanted this knife, I decided to go ahead and buy it after seeing their stock drop to very low levels (lest I miss the proverbial boat). l made damn sure that I checked the seller's feedback closely. I also paid with a credit card for an extra layer of protection. I'll note publicly here, at this point, I had done as much research as I could have before the purchase, and despite knowing I had done my part, I also accepted the fact that I could very well be stuck with a QC dud or worse, a fake.
Anyhow, the knife arrived a few days later and I'm happy with it; not a fake as far as I can tell and not an example bungled by the factory either. I was happy enough with it that I wanted to buy a second one for a friend of mine who has an upcoming birthday. However, this time, one of the (again, few) authorized Benchmade retailers up here had finally gotten some in stock (much to my surprise). So without any hesitation, I ordered a second Mini CR from
them (I'll add, between their list price and shipping, by purchasing from them, I probably paid a $20 premium - but well worth the extra peace of mind for me).
Ironically, they ship via Canada Post while the Amazon seller shipped via FedEx, and Canada Post has been messing around with my mail again so I'm still waiting for that second Mini CR to arrive.
I guess what I'm trying to say is (
TL;DR):
I'd never purchase a knife from Amazon, eBay, etc. If I could help it, and they wouldn't even be a choice for me
unless they were my only choice. If they happen to be it, then I'd weigh the cost of the purchase with how much I want the knife. Additionally, if the threshold for financial pain, should I be unlucky, were to be something I'd be unable to live with, I'd pass altogether and learn to live without. YMMV.
Edited for redundancy.
