When my Initiate v2 arrived, the screws were tight enough to have left dents in the polycarbonate blade. Are they supposed to be that tight?
Yes, it’s normal.
As Mercury Kung Fu says, they need to be just tight enough to keep the blade from coming out when you’re using it. If you are mounting this on the wall and never swinging it, performing flow exercises with it, or striking anything with it, then very little pressure, indeed, will be required. However, the more force that is applied to the blade (striking or swinging), the tighter the screws need to be. For how I use my blades (including the unintentional drops and unintentional strikes of solid objects like furniture, walls, appliances, the floor, or the ground), this means that there WILL be dents in the blade.
However, as MercuryKungFu points out, unless you’re pulling the blade out of one saber and putting it into another with a different depth in the emitter (or your emitter has windows at the same level as the retention screw, and you aren’t careful how you align the dent) in the emitter), the dents will be hidden by the emitter itself.
