Wilson Tactical knives are made by several manufacturers, several of which are based in the USA like Chris Reeve and Les George. Wilson Tactical itself is a Wilson Combat company based out of Berryville, Arkansas.
My favorite two resources to find the best deals on Wilson Tactical knives is either Blade HQ or their website.
