Many, many years ago I worked in a customer support center for a large retailer. On my lunch break I pulled my SAK Tinker from my pocket, opening the “large” blade to cut my apple. A female coworker, who I had known for quite some time, and who I never thought would have had an issue with it, got all weird. Her face turned to utterly appalled, and she started counseling me about having brought a “weapon” to the office. I never stopped carrying it, and HR never bothered with calling me. C’est la vie.
