Engraved/Polished Dura-ace seatpost

Got a good deal on a scratched up dura-ace seatpost. Decided to polish it, but wanted to keep the dura-ace logo. Ended up engraving/polishing some flames using a pocket knife, sandpaper, and Mother’s mag. Originally I just polished it but there was a pretty apparent transition line between the anodized aluminum and polished aluminum, so I got the idea to polish a pattern. Definitely not perfect, but this is what I did in a day.
