Size large - 1.75” (37.5mm) uses a 6 gauge needle. 

I went with a light blue engraving over a gold base. Doing a light color over gold sometimes hides the color on the engraving, so I typically recommend blue, purple, or bronze with gold, but this specific pattern allowed the color to show through perfectly which highlights the engraving tool paths. Against all odds I managed to match the blue on the pins bolts, and frames. These are different grades of titanium, and I assure you that wasn’t a simple task. They turned out great. Although it is not typical I engraved the pattern on the inside as well. This is a half day of engraving, but I felt the repeating pattern justified the additional work.

I’m asking half what the machine time would cost working on other products, but I understand these are still much more expensive than a traditional fish hook. Therefor I am taking offers.
