Just seeing this thread now - sorry if I'm too late, just wanted to chime about Grohmann knives.
I placed an order for a few knives maybe a year ago and can attest to the quality of factory seconds. At least in my case, I could tell little difference between the firsts and the seconds. On the topic of factory seconds, they also have factory second sheaths, which I found to be completely indistinguishable from firsts, except for he small "S" stamped into the belt loop (#3 sheath). Also, you'll see on their website that you can order some, but not all, knives in factory second condition but I found out during a call with them that you can pretty much order any knife and/or sheath in factory second condition.
I haven't used their knives much but can comment on fit and finish, etc. I found fit and finish to be pretty good but not quite at the level you'll find from e.g. LT Wright. Even on the flat grind #1 in carbon steel, I found the interface between scales and tang to be sharp - you can kind of feel the sharp edge of the tang. Also, the tang doesn't seem to be polished or sanded smooth, it's just a touch rough.
This probably won't affect the usability of the knife. Ergonomics are exactly as everyone says - fantastic.
One last comment about ordering from Grohmann - prices on their website were charged in USD, not CAD, just keep that in mind when you order.
