Use it when
The fit is obvious.
- · Reach for the Mirka 1×30 Belt Pack when the job is knife making, 1×30 belt sanders, and precision blade work: that is the fight it was built for.
- · Aluminum oxide is the reliable one: cheap, tough, no surprises and no complaints. It will outlast your patience before it outlasts the job.
- · 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 the budget is tight enough that value-per-pack matters more than top-end feel and longevity: good mid-tier paper will get you there slower.
- · Leave it if the surface is already close to finished: a belt will happily undo good work.
