I decided to start burning my signature on my pieces rather than use the archival ink pens. After some searching I settled on the Walnut Hollow Creative Woodburner Tool. You can find it on Amazon but it's good bit cheaper to order from Hobby Lobby - $60. I like that it comes with a ball point small round tip. I'm much better at my signatures with this tool than my pen, easy to control, burns well but not too intense, has temp settings, different tips, etc. I find setting at 7.5-8 on the dial works great for most all I sign.
