I was wondering if any one had used any knives that were made of 3V. I have several INFI knives and had heard that 3V rivals INFI steel in edge retention and hardness but is difficult to sharpen compared to INFI. I had saw this discussion (below) on BF about it and was wondering if any one has used a Fehrman knife before and how it compares to a Busse? I know how tough the Busse knives are cutting through concrete blocks, trees, bed frames, etc.. and still remain razor sharp plus being able to bend 90 degrees and spring back to true and I have heard that Febrman may be similar in strength but I have heard it does chip sometimes in extreme strength but most people would never reach that level unless cutting through aircraft skin. So my question would be if anyone had any experience with 3V and your opinion.
Thanks
