Hey I posted on your other post. I have a model 2.5 tanto in urban camo, a green g10 hak, a p1 toxic green bashido (US version), a urban camo pack knife, and an orange slcc. They hold up just fine and are great for edc light to medium use and great for self defense as that is what warren designed them for. To sharpen them you need something with diamond because of the hardness of the carbide edge. You can also go to advancedtacticalknives.com thats where i go now. The guy Michael Elman is a great guy and has helped me with some of my purchases from him. I know I have the same problem with WT knives they are just works of art I cant get enough of or look away from.
