Whiteheads Cutlery in Butte has been a cutlery store for about 100 years, years ago it was a wonderful place, still is kinda neat and worth checking out. I think they are still open, its been a couple years since I have been there, they had a web site in the past and maybe still do. They did have alot of old knives on display, but were not for sale, then again everything is for sale at the right price and many of the old knives have been sold over the years. There is also a store in Great Falls called Blade Master, they sell all kinds of gift items and a few knives, when they started - about 10 to 20 years ago they had mostly knives, but to stay in business they started selling all kinds of stuff. Check out the Jack
Club Antique Mall in Great Falls also- there are alot of old knives there too.
