Foursevens x Carryology Preon P1 Onibi

**The Collaboration Design:**The Foursevens x Carryology Preon P1 Onibi features their trademark pattern and color scheme. We went through many iterations and initially planned to laser engrave the pattern on the body. That would be the smart/logical approach. Earlier Preons had a rough machined texture on the body affectionately known as “the pocket grater.” I eliminated this on the MKIII Preons. Laser engraving titanium can leave equally rough edges. We needed the pattern, but what to do? The only option was to level up. We ultimately chose to CNC machine the pattern with a single point PCD diamond engraving tool. This single engraving operation takes 30 minutes for every light. That’s about 500 hours of machine time…just to cut the engraving. It’s a stupid idea from a manufacturing standpoint, but sometimes the "stupid" way is the only way to get the result you want ;) Ti Preons are a rarity. We’ve only done one other batch since I took over in 2018. Of course we use 6Al4V (Grade 5)
