The Oppressor V2's were a custom 25 unit run made exclusively for BladeJunkie. They are 20Cv, have a steel lock bar insert, the Holback rolling detent, and ceramic bearings, were anno in FF standard colors, and have custom milled titanium clips. I saw them at the shop while they were being made.
If there is anything else you need to know about them, you can contact Chris at Ferrum Forge via their website.
