Because some employers or potential employers are misguided, there is a legitimate reason to use a handle instead of a full name on some forums. HR departments everywhere love having the ability to search social media for dirt when they need it or want it. I've seen it multiple times in my past employment. Every single HR person I have met has talked about doing searches on employees and forming opinions on their suitability for employment.
If you are making knives to sell, and it can't negatively impact your employment, I would strongly suggest using your full, real name. Not every employer would have an issue with knife making but certainly some would.
I am self employed now so I don't have to worry about that.
I use the handle bossdog here because there can be only one.
I am Tracy Mickley and I support this thread.
