I've had good and bad experiences buying online. Mostly good. The main disadvantage is not seeing and touching the knife you're buying in advance, but most reputable dealers have reasonable return policies. Shipping can be a huge pain, especially across borders, but that is another story. Make sure the delivery is trackable and insured. Check out the "good,bad and ugly" forum for comments on specific dealers. The better dealers are really quite good. I can personally recommend Arizona Custom Knives, Skylands, The Knifecenter and Les Robertson. These folks are knowledgable and very helpful. I'm sure there are other excellent ones, but I haven't dealt with them myself, yet. I've never heard anything but the highest praise about Chai Cutlery. I do suggest that before you order you actually make contact by telephone. Ordering from individuals and makers is more variable, but the same principles apply.
