With these hammers I used as before the dremel with the disc cutter point. Put the hammer in your vise so both hands are free so you have more control of the dremel, and remember to wear all your eye and face protection. On the orange hammer I made more precise cuts following the lines I drew on the hammer head before cutting. On the other hammer I just cut randomly, sometimes I prefer a texture that isn't uniform or precise. You can click on the pictures to enlarge the photos.
