CTS-BD1

A relatively-new steel from Carpenter Steels, designed to be nearly identical to GIN-1/G-2. Used in the lightweight FRN versions of the C94 UK Penknife.

Sal Glesser posted on BladeForums.com in 2010:

"Another steel that was specially formulated to our request is Carpenter steel's new CTS-BD1. This is, in my opinion, an optimal formualtion for a blade steel. It is based on Hitachi's well known "Gingami I" (silver paper), also knows as G2 (early Spyderco's) and GIN 1 (current Spyderco's). CTS-BD1 has been "tweaked" by Carpenter's metallurgist, Rick Gleixner and the result is very nice, and USA made."
