Gerber Swagger Assisted Opening Pocket Knife

I ordered the Gerber Swagger Assisted Opening Pocket Knife and it has arrived but I am disappointed with it after opening the box the knife wouldn't open with the spring assist i oiled it and still wouldn't open finally i had to get a pair of pliers and grab the blade and pull it out to open it, I worked the blade open and closed thinking it was just knew and stiff but to no avail, it will not open with the spring assist. I thought I was buying a good knife by it being a Gerber but I got to reading the fine print and of course you know it's made in China, not what I expected from Gerber knives. Just my $00.02
