The "original" ruby-tipped spin tops: crafted without compromise 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. Any machinist will tell you that the most accurate part is the one machined to completion without removing it from the machine. Any top that is machined on one end, flipped, and machined again is guaranteed to be less accurate. The more times you hold the part, the more error you introduce. Materials: The C360 brass used in the ring is a Zinc/Copper alloy. Brass is heavier than anything but much more exotic metals. Brass is a "free machining" material, which means it machines VERY consistently. Materials are rated for machinability on a 100% scale. C360 brass sets the standard at 100%.Tougher materials resist cutting which wears the tools faster and leads to less uniformity and "out of tolerance" conditions. Contact Point Options: For complete information, please see the "contact points" tab on this page. Of course the ruby is the ultimate in performance and awesome...can't beat that combination. It's a little bit fragile if you compare it to a Mac truck, but a little bit of knowledge and care will keep it spinning for a lifetime. I mean, it's nearly as hard as diamond and those are "forever." >>> Broken contact balls are not covered under warranty. NEVER drop the Lambda top onto a tile or granite surface or the ball may shatter. Contact points can be replaced in tops that have hollow spindles (all current models)...assuming there isn't other significant damage to the top.
