Oh i understand that part Bruno. I was just wondering about the cost of the steal. Like are we talk8ng 10 bucks or 40 bucks or more just in money for the materail on a blade. And of course with different types of material and layers and such its going to change too. Just curious i guess. And of course you cant buy just the size you need so being a plate much bigger to start with devided by the amount of blades you can get. Its all french to me right now. Maybe next year ill make the meet and learn something.
