Very nice looking pen!
So, I started using my regular table saw to do these with a 1/8 kerf (0.125). I too thought it was too thick.
I went to the lowes and picked up a frued 7 1/4 inch thin kerf blade with a 5/8 inch arbor hole. I found it had a kerf of about 5/64 (0.078125). That works quite a bit better for me.
I'd still like it thinner, but the 7 1/4 inch blade was pretty cheap.
It cracks me up however, when I think about how good it works in my 10" grizzly cabinet saw. IT's a bit of over kill...
(And to think how much my woodworker II blade cost....)
