Of the people who carry a $100-150 knife, 99% don't have any time or interest to be engaged politically about their next knife-buying decision.
Of the 1% who do, 10% care about this issue at all, and of those, 10% will stop buying Benchmade completely, and of those, 10% will even stop buying from any dealer that carries Benchmade at all.
So Benchmade will lose 1 out of 10,000 customers, and Benchmade dealers will lose 1 out of 100,000 customers.
Let's say those customers they lose are the "knife guys" who spend on average 100x more knives than normal people. That's a 1% sales hit for Benchmade, and a 0.1% hit for dealers.
