I've been carrying the BK10 Crewman for a year while waiting for my Randall 25-6" to be made (only 3 years to go <img src="/images/graemlins/tongue.gif" alt="" />). The blade on the BK10 is actually 5.5" which is pretty close to what you are recommending. I had ordered a BK7 7" along with the Crewman and ended up selling it because the Crewman was just about perfect for my needs. I especially like the stout tip. When Doug's new Becker fixed blade comes out it's going to be interesting to see how it stacks up.
