Thinking about a mark/stamp for my work

Yes, I got the idea from Chrisand thought it was cool.  He had a stamp made of some dividers which has become his identifying mark.  I thought I’d come up with an identifying mark, perhaps of a tool I made.  I’ve made a dovetail saw and a panel gauge; so using those as a mark and then, perhaps, adding my blog handle to help make the stamp unique.  Here’s a couple for consideration:

Dovetail Saw
Panel Gauge
This gives a little bit of an idea of what it would look like.
Here it is with out the Logo.  Better?

Ever thought about doing this?  Any lessons learned?
