That's a silver knight on top, right? It looks to be around 3 3/8" or so? Which model is that, if I might ask? (All I know is there were several sizes and they were named numerically.)
Good looking mini-copperhead too -- been fixing the lack of pocket-time for my blue one this week, myself.
That knife is a 250A model. It is 3-3/16" long closed. The blade is 2-1/2" from the bolster to tip when open. The other sizes are 200 for the small one and 300 for the large one.
The 250 size was the most varied model with covers of wood, all stainless, full wood onlay, white pearl like the one above, black pearl, green kraton rubber (checkered), bone, stag, white scrimmed micarta, black scrimmed micarta. There could be other variations I'm not aware of. The 200A was available with wood, pearl, all stainless, and abalone. The 300 models were less varied than the 250. The 250 size also came as 250B with drop point main and sheepsfoot or pen secondary, and the 250C model with a stockman like layout with the drop point main, a sheepsfoot secondary and a pen for the third blade. The assembly of the multiblade knives is pretty phenomonal; the clearance between liner and auxiliary blade(s) and between the auxiliary blades and the main and/or each other rivals the fit of many backsprings we see. Yet they do not rub each other. On the 250C I have the main rides close to the outside scale, but doesn't rub; I don't know if that was intentionally done for clearances or just the one knife.
Reading this post, you might think I am infatuated with these knives, and I am to a certain degree. I just bought a 250A in kraton a week or so ago. I've given a couple away here over the last couple years.
Oh, and I really like mini copperheads too.
