I asked myself the same question about the lack of discussion on the Hogue knives, especially considering how well the EX04 is constructed. I have just started getting into knives and have found this forum to be invaluable. This is in fact my first post. After two months of research on this forum, I have learned a considerable amount and have finally made my first purchases: Spyderco Sage 1, Spyderco ParaMilitary2 Black Blade/Camo, and the Hogue EX004 4" Tactical Wharncliffe with Gray handle. I have selected these knives to fit almost every need, though I might need a Spyderco Salt 1 serrated to complete the collection. These knives have all been bought to be used, as knives should be, but I must admit that the Hogue EX04 is almost too beautiful. As stated in this thread, the locking mechanism, the handle, the blade, and the fit are all tremendous. I am sure that some may argue that they would prefer a different steel than 154CM for their collection, but since I plan on using it and sharpening it myself, it is probably a good choice.
Thanks to all who contribute to this site. It has helped me tremendously in learning about knives and I think helped me to make some good choices for my first ones.
