Cool, Brian. Do you have it yet?
I've handled one of those before, and I think they did a nice job, especially for the price. The design they chose is slightly unusual in that the grip is very long. You can't really tell until it is in hand. When I say unusual, though, I don't mean innacurate: There are period images of rondel daggers with long grips, they just aren't the most common. So this design is quite plausible. They did a pretty good job on that particular piece, in my opinion.
I've got the Arms and Armor one that Ed linked to... that is a *sweet* dagger.
Much more so when you actually hold it. (You know, Ed, A&A is having a 5% off sale right now, and have announced that they will be raising prices in July...)
