i emailed knifeworks about the blade,just got it back today, he says it will be satin finished.foliage green might be similar to the spyderco military d2 handle. as far as m4 steel;.CPM M4 High Speed Tool Steel
--------------------------------------------------------------------------------
CPM M4 is a special purpose high-speed tool steel, containing a high level of vanadium. M4 is tougher and more wear resistant than M2 and M3 in high speed cutting applications involving light cuts.
CPM M4 also comes in several modifications including high carbon (HC), which offers a better hardening response during treating. Additionally, the high sulfur (HS) modification, standard in larger diameter stock, allows for improved machinability and grindability over traditional M4 steel.
As with all CPM steels, CPM M4 us created using Crucible’s patented Crucible Particle Metallurgy process, which provides a highly homogeneous, stable, grindable, and tough product compared to steels created using traditional metallurgy.
