I received a new Cold Steel Hold Out II model in the mail and the back spring was extremely stiff so closing the knife was difficult and deployment slow due to the stiff spring. I was wondering if I got a lemon or if that is a defect in the entire model? It has the Tri Ad lock so are do all these knives with it come with a very heavy spring? I am returning the knife for a refund due to this as I don't think a $65+ knife should be this way. Anyone else have this experience?
