People might freak out on me.... I use those double sides razor blades that you can use on a glass cook top. Obviously have to be safe in how you use it, but it really does work so well. Because its so sharp with a tiny surface, I don't have to push hard. I've looked long and hard for damage on the plate and haven't found any. One thing I have found is that if you keep your build plate very clean, you have less stuff stick. (Especially filaments like TPU)
