My guess is, if there was any stipulation about creative control it is limited in time. I also guess the entire operation will become extremely cost-sensitive. That is all too often the pattern of these buy-outs.
As you rightfully state, they are not in it to advance the industry, only their bank accounts. They often milk the brand for all their worth while churning out increasingly sub-standard products and then bail when things start taking a turn.
Along with Gerber, ask Marlin/Remington/Bushmaster how the FGI/Cerberus buy out went...
I can see them trying to retain the same designs they have today, well the high sellers, but shift production to China. That in itself doesn't automatically equal bad so long as they stick with quality makers and allow for sufficient per-piece manufacturing costs. I suspect new models will become increasingly targeted at low-level offerings with strong attempts to penetrate retail shelf space. I can also see a big push in the tactical weapons segment, but again, with a huge shift to Chinese-made budget quality.
What is Cold Steel's USA manufacturing foot print? I only ask as it might be a point of interest to watch for it staying open as I would guess it has the highest operating costs.
