The D2 that Manly uses is German made, so not Chinese mystery D2 steel. Have heard good things about the S90V but have not used it my self. I have a Comrade and a Drugar in cpm 154 that are waiting to be tested.
Now next question,I have contacted Manly USA, my clip on my Peak got bent after snagging some fabric, anyway to get a new clip or replace it with a metal insert? I have heard that you can get the insert if you want to take off a clip, are they necessary to keep the handle slabs tight? I also ask because I may take off the clip on my Comrade to see if it will fit a medium leather belt sheath.
