Sigma is a deviation of Gamma with just a few changes and refinements. Its still a futuristic/cyberpunk pocket katana.. But the focus of Sigma is on the wharencliffe style blades, the handle accommodates them more seamlessly while providing for the best blade to handle ratio and allows for a backspacer-free configuration. Still ~4in blade, 3/16th inch(0.1875″) thick which puts it in the “moderately overbuilt” category. Right now in S35VN steel.

Ceramic bearings and detent ball.

The blade to handle ratio has been improved from Gamma and the clip is now blind screwed.

Cool feature of this design is that I integrated an even wide range of blade types into it, maximizing the customization potential.
