A little more -
Between the Contego and the 940, I would prefer the 940. I think the design of the Contego is probably going to be more polarizing, and I also like how the design of the 940 isn't too tactical. Also like how the 940 takes up a very small amount of room in the pocket.
Another BM to consider is the Bugout. Also very easy to carry, and has the ability to be greatly customized by the owner should they desire. Less expensive than the Osborn too.
You might also consider the Spyderco Paramilitary 3 and Para 2. Both made in America like the BM's, and can also be greatly customized like the Bugout. I prefer the Para 3, but the 2 is more popular overall. I love my 940-1, but I carry my Para 3 more.
Lastly, Filson has their own variant of the venerable Buck 110 that I find to be a very handsome knife. $130.00, with a belt sheath. If your co-workers are the Filson type, then it might be worth your time to call them.
