Is the black part of Katana universal ABS plastic like in the new classic line?
Probably not.
The black portion is textured like the tan portion.
It also has indications that it's been cnc'd.
So, in the description on Nobles website it says for Katana and Kayten (oops sorry K10):
"Updated Noble universal form factor and geometry featuring creative precision machined aluminum housings"
And for the others it says:
"Updated Noble universal form factor and geometry featuring precision machined aluminum faceplates"
So - Katana is all aluminum as far as I can judge from the description.
Cheers!!
