I've seen that at tool, but it's too flexible to work well. Tweezers can work, if used skillfully, this tool removes the guesswork, and allow you to concentrate on the tick!
I'm glad you're making one, that's why I posted this! The vets still fight over this tool, so I need to make a few more.
I used a grinder on the first one, but the file is safer for a novice to use. The Dremel will do you a good job, enjoy!
