I'll not comment on the logo content as a stamp, but offer a couple of general thoughts on using the logo as a business name.
- If you're trying to tie the logo and your name together and want to use it as your business name, you should check with your state business license registrar to make sure what you want to use is a unique name that can be licensed. That registration will determine your name on your form of license (LLC/Corp,etc), Federal Tax ID, bank accounts, checks, etc.
- You also may want to consider tying the business name to a unique website URL (say, MBaroneknives.com) or some easily remembered variation of the name. Checking availability of that name may drive your logo decisions.
- And you also might give some thought as to the future of the business. If you think you'd like to sell the business some day, you might consider making the name generic versus using your own name (say SuperDuperKnives LLC vs Mark Barone LLC). A generic name may sell easier than your personal name.
...just some thoughts to kick around...
