I hadn't read anything about that, but it looks like the only models with Charcoal Dymondwood handles in the 2013 catalog are the Vantage 341 and 346. The Charcoal and Yellow Delrin (Comfort Craft series)are no longer listed either in the catalog or the price list for 2013.
It's a shame if true, They're my two favorite handle options for the slippies.
