It seems like all of the knife makers are increasing their prices, at least it looks that way by reading Blade magazine. Much like so much of the sporting goods industry, they are riding a wave of popularity and demand,; as long as folks are willing to spend more money for their products they will continue raising prices. Just look at the crazy prices for bows, cross-bows, firearms, etc.
If people would refrain from paying the exorbitant prices, vendors would have to drop their prices or go out of business. Many auto dealers learned that you make money with lower prices but increased volume.
