I don't have access to BRCGS standard since it is copyrighted and behind a paywall, so I can't review it with you or cite sources.
In my (different) audit standard, sharps and metals are aimed at preventing contamination of the product.
So, a knife used to cut rolls of plastic film would need to be controlled, just like you said.
This knife touches packaging and has a chance to introduce foreign material (blade chips, handle fragments, etc.)
These will need to be checked at a higher frequency since they're used every day. Maybe make it a part of daily GMP checks.
I imagine they use "sharps and metals" to describe knives and utensils that are used often and in direct contact with packaging.
However, a screwdriver or tool used inside a maintenance room away from production is much lower risk.
I think the easiest way to cover all your bases would be completing a separate checklist at a defined frequency. (monthly?)
You could fill it with all the utensils that aren't used often.
Then if you're ever asked, you will have records EVERYTHING is being checked and potential issues will be corrected.
Example:
Clean, in good repair, no missing/chipped pieces, proper storage?
Knives: YES, all knives checked, no issues found
Maintenance Tools: YES, all tools checked, no issues found
Scrapers: YES, all scrapers checked, no issues found
Box Cutters: YES, all box cutters checked, no issues found
Were any damaged, soiled, or improperly stored metals/sharps found during inspection?
NO, all metals and sharps were clean, undamaged, and properly stored.
Corrective Action
No corrective actions required.
