Deff Japan is back at it with its new flagship Cleave Zero, a handsome all-aluminum machined bumper featuring a screw-less brass joint design. Shown off in its polished and anodized gold hue finish, Deff's new Cleave Zero perfectly matches Apple's golden iPhone 5S and makes it clear to everyone that you sir or madam, have the new iPhone 5S.

The Cleave Zero features a beveled-edge design crafted from a solid block of aluminum and split into two parts for easy slide-in installation, integrated machined aluminum button and silent switch controls and a rotating finger strap mount that can be used with Deff's optional carbon fiber-made ring finger adapter instead of the normal wrist strap. Oh and yeah, there's a silver version too and it looks pretty awesome on a Space Gray iPhone 5S. Deff's Cleave Zero is scheduled for release in Asia on October 1st for around $100. Deff's Cleave Zero will most likely be named differently once it hits North American shores under the Draco Design brand. We assume it'll go by the name "Draco Zero".

What's this? A new and slightly more improved Deff Cleave aluminum bumper case, a.k.a the Draco 5 in North America. It's an unreleased Japanese model that'll soon be available world wide. The Cleave Aero by Deff is the same three-dimensional and insanely curvy CNC machined aluminum bumper as the Draco 5, with one difference in that it features a TPU bumper on the inside that'll provide better shock-absorption and complete isolation from metal on metal contact. Each Cleave Aero comes with one red and one gray thin inner TPU bumper that you can see forms a parameter around the front and back sides of the iPhone 5 while also serving as the Aero's volume and power buttons. Gone are the integrated metal buttons and the silent switch. Deff claims the new design of the Aero will not interfere with signal reception.

It's an interesting new look for the Cleave and soon to be Draco Aero that will let users color-customize their bumper straight out of the box. There will only be two color options including a white colored Aero called the Luxury that features a glossy powder-coat finish that closely resembles that of a car's paint finish, and a matte anodized black Aero dubbed the Dark Knight. As for price, the Aero will go for around $90 when released in North America.
