Your point about Jim Mattis is well put, Jim; he is truly a honest, concerned gentleman. I have yet to order anything from him, but wouldn't hesitate to do so.
My two favorite internet dealers are Northwest Cutlery, from whom I get most of my mid to low end stuff. They are friendly, honest, informative, and a pleasure to do business with. Things are shipped rapidly and arrive in good condition.
Arizona Custom Knives is my other favorite dealer. I have ordered several top end items from them, and each has been as described, delivered promptly and in good conditon. Their catalog, which they mail, is useful, as well as their website catalog. I just got a Chris Reeve Large Sebenza with tear drop Damascus. While I was waiting to call them, I just thought I would look through their catalog they had mailed me. WOW! A Kit Carson folder with Stellite blade and C-fiber scales; I just had to add that on! While talking to Jay, I asked him if he had any Mad Dog Knives. He said he had just got an ATAK2 in the day before. Bingo! another addition. The knives arrived, four days before Christmas, less than 24 hours after my call!!
I use a credit card with most dealers out of convenience. Some want money orders or cashier's checks, and I have no problem with providing them, IF I know the dealer is reliable.
I have had only one bad experience with a dealer; he supplied me with knives I felt to be not as advertised. I asked for, and obtained permission to return them for correction. After 3 months, and no knives, I asked him for a refund. He agreed, by e-mail, then reneged. Fortunately, my credit card company issued a charge back to my account. The merchant was allowed to state his case, which in the final version was that the knives were perfect, he had received them back, but still wanted payment (they were not custom made). Needless to say, the credit card company sided with me.
I don't worry about credit card numbers being stolen. I am not liable for any fraudulent charges, and they keep close tabs on charges; I received a call the day following my order with AZCK, from the credit card fraud division wanting to know if it was a valid order.
Thanks to all of you internet dealers with whom I have done business. You are a good bunch, and I wish you well. Walt
