I'm not into knife fighting but I am a fan of military history, and arms and uniforms of our past military.
From what I understand I believe if you use a knife and a gun, the knife should go with the strong hand, the gun which is easier to use and requires less strength should go in the week or off hand.
If you'll look at military uniforms from periods where the sword and gun were used, the sword was on the left side, but arraigned so that it could be drawn with the right hand (cross draw). When you look at the holster it is also arraigned so the butt of the revolver points toward the front (cross draw). Being set up in the cross draw position for the left hand it also can be drawn by the right hand. Its more difficult to draw a pistol/revolver with the left had if the holster is set up for the strong hand draw (butt facing the rear).
Its easier to shoot weak hand then it is to use a knife with your weak hand.
