JT, I have all 3 of the BMs mentioned here so far. The 770 lives in the knife drawer as does the 690. IMO the 770 is too small / thin and the 690, although fancy is too large for office and airport carry. Guess that leaves the "clipless" 850. It's fancy, under 3" and is plenty stout. Carry in a William-Henry clip sheath IWB might work well for you and it would protect the rainbow anodizing from pocket wear while still allowing easy access. The 705 is another good option. My EDC for office and travel is a William-Henry Kestrel with amber bone scales, but I swap it for the 705 as soon as I'm home. One problem with the 850 is finding one without serrations. Good luck.
