In 2012 they got some flak from saying they won't co-brand with any weapons manufacturer. Guns, knives, bows, what have you.
From their clarification letter:
"In the past, we made our logo available to appear on wide variety of products, including guns. As an organization, we owe it to our donors and constituents to maximize the return on investment of our dollars and brand. We are always looking at our business practices and whether we should continue with them in the future. In the case of cobranding, we’ve decided that we’re not going to offer our logo to appear on weapons anymore – whether they’re guns,
knives, bows, swords, or any other type of weapon. There are still a few of the guns around for sale that had licensed our logo years ago, but there aren’t any new ones being made. This is purely a business decision based on a review of a return on investment, especially when compared with other types of cobranding ventures."
I guess SAK's aren't really knives
