I like Smoky Mountain Knife Works. I've gotten some very nice deals from them, and I've never had a problem, including on a return.
But their catalog is full of Frost knives! and the occasional typo or outright error ... and their website is down too much. But I've also never had a problem ordering online, which is how I deal with them now. It's just frustrating that the site is hard to access, but hang in there! When it works, they've got a great slection and a lot of incredible prices.
