Use it when
The fit is obvious.
- · Reach for the Norton Crystolon Combo Stone when the job is sharpening blades, chisel restoration, and tool maintenance: that is the fight it was built for.
- · Silicon carbide bites sharp and fast, and it loves water. Brittle, brilliant, a little reckless: the grain that leaves glass when you keep it wet.
- · This is the working middle: enough bite to matter, refined enough to leave the job somewhere worth continuing.
Skip it when
The job asks for something else.
- · Leave it if you are actually solving a different stage of the climb than the one this pick was chosen for.
- · Leave it if longevity and cut speed matter more than the price: cheap abrasive is cheap for reasons you feel on the tenth sheet.
- · Leave it if the work is edges, profiles, and tiny repairs: those are easier to control by hand.
