First post on BladeForums. Been into guns, and now getting into knives. Bought a few ESEE's (4 & 5) and now looking at a nice folder. Want to get a Benchmade, but have a question about their great warranty/ever-sharp deal. Does the knife have to be purchased from an authorized dealer to get any work done on it? There are many preowned ones I want, but also want to have the option of sending it in to them any time I want for some maintenance. Sorry if this is a commonly known fact, but not to me being new to this hobby.
