Luftverk EVORA R-SP
The R-SP is the new raw version of the Evora. This un-coated beauty uses a different grade of titanium generally reserved for medical implant uses and is stronger than typical Grade 3 or Grade 5 titanium. This experimental choice in material created a bunch of cost and machining challenges. Comparing to the first run, the differences in design are very subtle. The most noticeable is the chamfer on the center nub. Otherwise the shape and dimensions are exactly the same.
R-SP stands for Raw - Slow Pass. "Slow pass" or Slow finishing pass is the last step in manufacturing a yoyo. It is when the cutting tool goes over the whole yoyo one more time and gives it its final finish. For yoyos that are being anodized, beadblasted, or satin finished, this can be pretty quick because it doesn't matter. For yoyos like the Evora R-SP, this is excruciatingly slow. The SP adds an extra 30 minutes to each half. The regular Evora already takes 1 hour at normal speeds without this pass. to put it in perspective, It takes about 2-4 minutes to machine an average Aluminum Yoyo.
This final pass is the key to battling chatter - which is difficult to avoid with hard materials like titanium, let alone this mutant grade. On the R-SP, the final pass is so slow, it looks polished - but isn't. In fact, there are micro grooves that make it have an iridescent rainbow effect. You can kind of see it in the pictures. These are also the highest quality, and smoothest Evoras ever made.
A simple hand stamped box with a butcher wrap protects the yoyo during transportation. The bearing has been updated to a ceramic ball bearing (Races are stainless) compared to the dreadfully expensive full ceramic in the standard Evora. These small yet effective changes help offset the more expensive material cost, keeping the price as reasonable as possible.
