I've Carried my Texas jack quite a bit over the past year, and have gotten really familiar with it and it's secondary blade as I modified it.
Originally I just wanted it to look better and my modification was the easiest without touching the edge.
With this

I felt the knife looked better and the secondary blade was perfectly serviceable, but I have come to desire a small sheeps foot for this knife so I decided to bite the bullet today and go for it.
Over the past year the secondary blade has come to look almost factory, but it's going to take some time for it get back to that point.
Overall I'm as happy with my work this time around as I was last time, I only lost a couple mm and while I wish I could have kept the width the same I think it's functionally just fine.
It came out nice and straight as a sheeps foor should be too, and thing I'm happy about.
