I am active duty, and I recently purchased the CRKT M21 spear style folder for about $20. I did a little research and decided that the AUS-6 would be good enough for day to day jobs. I cut everything from 550 cord to rubber hoses to insulated wire cables. Will this knife be reliable mechanically, and will it hold its edge fairly well for moderate daily use? Also, if anyone has any suggestions on good field knives (folders or fixed) with the blade not exceeding 6 or 7", I would certainly appreciate it. After all, the knife can be one of the most important tools in the field apart from my rifle, 550 chord, and duct tape. Your advice and opnions are appreciated.
