Honestly guys the grind lines on this knife are smoother than you think my camera not so good so but to answer another question yes you can notice the grind lines with the coating on under light. Which is one reason why Blake wanted me to blue it and as far as use he has had no issue with knife dragging or otherwise. I would say another thing is the coating almost instantly came off with took less than 20 min which to me using it with coating would not have kept the grind lines hidden or filled in for that matter if it came off that easily.
