We could easily do a full hippo handle if you'd like. We can source a straighter tooth, or the curved carver if that's preferred. However, I do think for the sake of contrast the just a spacer would be ideal, moving with a darker handle. I'm not going to say bluish FWI isn't doable, but it will definitely increase lead time as we'll have to do some searching. Giraffe would be a quick substitute, but again, I personally think hippo in the middle would be awesome. We could go with ebony, or ironwood for the handle, buffalo (fluted or not), maybe a blasted finish micarta?
