I highly suggest you check out the Case 5279. It is stag instead of jigged bone, but go check it out. There are always a number of them for sale on the the big auction site. I carry one regularly; they are great. Just like the knife you showed, but stag.
Edit: I just saw your comment above about not looking for a senator. I believe the 5279 is a senator-type.
