Could someone please help find an explanation of this please?
i mean how does it prevent an injury in catering?

Having a strong handle on your knife and being able to comfortably grip it usually means that you are less likely to hurt yourself with the utensil or knife. If the grip is uncomfortable or slippery in some way, then you may be more likely to drop the utensil or knife, or hold it in a way different than you normally would, which could lead to an injury.

Hope this helps! :)

Hands can get sweaty and slippery so if you accidentally drop your knife, it can cause an injury.

Explanation:

The grips on knives reduce the percentage that you can lose the grip on your knife and cut yourself.
