Hi Yvo,
Welcome to the forum. Well Yvo it's all about control and numbering the knives and issuing them to individual personnel will give you better control.
Like Charles said fixed blade knives are good. You can also get changeable blade knives such as the ones in this picture.

The top one is a foldaway penknife, the middle one is a manually retractable scalpel and the bottom one is an automatic retractable. All are good, as they do not have snap off blades. As you can see the knives are engraved with a unique code. Personnel can be issued with a knife, which is then their permanent responsibility. The knife issue can be recorded on a master knife issue list like this attached example:

When a new blade is required the operator takes their knife to a Supervisor and they change the blade and this can be recorded on a document like this attached example:
Blade_Control_Record.doc 50.5KB

If the blade is lost or damaged then there must be a review and details can be recorded on the backside of the above document.
Such a system may seem like a lot of hassle but it is relatively straightforward to set up and provides a high degree of control in terms of management and safety of the product.
Some further good practice points to consider:
- Do not allow operators to bring in their own knives
- Specify the type of knives to be used (don't forget to sample the operators first)
- Do not allow operators to take their knives home
- Provide sharps bins for blade disposal
- Provide some training or at least an explanation of the requirements to operators
- Add to GMP Audits (Are their any blades/knives lying about? Any uncontrolled knives?)
- Purely from an Health & Safety point of view you wouldn't want sharp objects left lying around on machinery or equipment.
Hope this helps.
Regards,
Simon
