Guido,
The carbon steel is a bit earlier. The stag is "slab side", or flat side. One of the topics at the blade show Q&A that Scott and I fielded was regarding "slab side" knives.
At this time only the "Cattleman" and "Stanaback Special" are available with this handle shape. I didn't know that, but apparently to reduce time spent per knife this option has been eliminated. Because the Cattleman and my dealer special have always included this option, they were spared.

Hope this helps, Capt. Chris
