I have CRKT First Strike blale that is badly chipped and dulled. The knife itself did not cost a lot but has been a very good blade. I used it for just bout anything and everything on my first deployment. I am new to sharpening knives and would like to save this blade but need some advice on a good sharpening stone and a good website to get them from. I am currently working on deployment number 2 so I have to be able to order the stones. Any suggestions?
