Your individual results may vary! LOL! I still tend to be a little heavy handed when wielding a blade.
I have had good luck sharpening the so called disposable blades. Best thing is to replace them before they are really dinged up. If you can see flat spots with bright light and reading glasses then they need to be stoned, use a hard stone to see how it works. If you start with a soft or coarse stone you will be starting over increasing the difficulty. Any of the hard stones over 2,000 grit should work and 10,000 is not too fine if it is only a touch up.
If you catch them before major edge damage then just stropping can be enough to re-align the blade and bring back a scalpel type edge. I had lots of practice sharpening inserts for broad heads, lost a lot of blood on the learning curve.
