Raptor is a titanium ring with a single
retractable blade that pivots out. It gets its name from the curved
slashing claw of the Velociraptor. The stainless steel blade can be used
to open boxes or cut packing tape or can be used as a last line
The ring is custom made in exactly your
size. The width remains at 6.3mm. The Brushed finish
seems to work best, so I left off those options. The
inside of the ring gets a polished finish for comfort.
Although the ring can be engraved,
the internal lines will affect the letters a bit. I
recommend the Roman font if you will be engraving inside.
