There may still be a Stoddard's Cutlery in the Chestnut Hill Mall. I remember when I was younger taking the T into Boston and going to Stoddard's when it was off Park St. They had a lot of high end knives. The last time I was in the Chestnut Hill Stoddard's, they had some Randalls and some other custom knives and some high end and higher priced production knives. If you are looking for users, you can always try the Kittery Trading Post in Kittery Maine. There's a Bass Pro Shop in Foxboro I've been to once. I haven't bought a knife in years, though, and I haven't bought from a store in even longer.
Good luck and let us know how you make out.
