I did find this information on SAKwiki in the Pioneer section. I guess I didn’t look there properly before.
Specifically the Black with black shield:
“In 2008 Victorinox produced the Pioneer with both black and red Alox scales in some markets. Like the Farmer models with the color Alox scales, these were likely a limited run. In 2011 two additional runs of the black Pioneer were made for US dealers”
Specifically the black with red shield:
“2012 January black Alox with red shield Pioneer. It is uncommon to have the red shield background on any Alox knives other than with silver or red anodizing. The red shield background with the black anodizing creates a nice contrast that highlights the shield more than just the regular silver outline. Limited to 50 pieces, numbered and dated, the engraving on this model runs parallel to the length of the blade, and appears on the reverse of the blade, which is different from the previous numbered special-runs.”
I’m going to go back to see if I missed anything else again.
