I've been a customer of A.G. Russell since about 1997 or so, when I was still in elementary school. To be perfectly accurate, my dad was their customer back then, but I was the enthusiast. They have always been great to both of us. I remember getting a beautiful A.G. Russell Fruit Knife for my birthday, and the next day doing something stupid with it and somehow breaking the spring. I was heartbroken! But they sent me another one, no questions asked.
And my first very high quality knife came from them, a Bob Dozier Professional Guides Knife that I got when I was in middle school (I saved up for half of it and the rest was given as a Christmas present).
A.G. Russell is what got me into knives, and their customer service has always been superb.
