Double cut is actually referring to a sandblasted finish. Satin is shiney steel while DC is like a matt finish.
My # 1 is Green blade, Black mag paper handles, choil, swedge round butt
# 2 is tanker gray blade, Black canvas mags, no choil, no swedge, round butt
#3 is green blade, Black/Green G10 mags, choil, Swedge, and round butt
would love to have a Black/Orange G10 with DC finish, but getting a little pricey
