SUPERIOR PRECISION: The "solid" variant of the Lambda top is machined from a single piece of solid bar stock. This consumes 4x the amount of material compared to the two-piece tops, but it also delivers a more perfect spin. . MATERIALS & CONSISTENCY: The C360 brass used in the ring is a Zinc/Copper alloy for toughness and machinability. C360 is a "free machining" material, which means it machines VERY consistently. . RUBY CONTACT POINT: Of course the ruby is the ultimate in performance and awesome. You can't beat that combination. A little bit of knowledge and care will keep it spinning for a lifetime. It's nearly as hard as diamond and those are "forever." . MADE IN USA: The Lambda top is made in-house on the Haas CNC lathe purchased with the funds from the Kickstarter campaign. All of the raw materials, including the instrument-rubies, are domestically manufactured. . Limited Lifetime Warranty . The "original" ruby-tipped spin tops: crafted without compromise. Good design is all about balance and simplicity.. . Lambda. The Lambda name is derived from the Greek letter "L" which is the physics symbol for angular momentum; the Newtonian principle that keeps a top from falling over. . Ruby. The secret ingredient (beyond a solid design based on Newton and "the physics") is the instrument-grade ruby sphere. You heard me right, I said ruby. This type of manufactured ruby is used in things like Rolex watches, super-precision measuring instruments, fiber optic transmission lines, and other really expensive and/or sciency stuff. The perfect sphere means there is always a perfect point of contact with the surface, wasting less energy and spinning longer. It also means the Lambda is better able to spin along its axis; therefore, it does not exhibit the large amount of precession (angular wobble) that you see in a traditional top . What's up with the hole in the spindle? That is 00% physics right there. Brass is more dense than aluminum; and making a top out of solid brass moved the CG (Center of Gravity) slightly higher when compared to the aluminum top. If the CG is too high the top will not want to stabilize. I tried a number of strategies to lower the CG on the top. . Like the discovery of Champagne, it was a happy accident. I'm a scientist at heart, and that is one perfect, beautiful 0.60 x .25" hole because it's EXACTLY what was needed to drop the CG right into the sweet spot for a perfect spinner. I bet you start to see this one on "other" tops out there in top land. It didn't take long for people to catch on to the ruby thing right? I don't mind that (much) but there's still some value in life for being the "original." . The Lambda was the first spinning top to feature an instrument ruby contact point and many imitators followed. Accept no substitutes. . . .
