nccer 00103 - introduction to hand tools 56min the safest utility knife has what type of blade? self - retracting folding replaceable plastic

Explanation:

In the context of hand tool safety, a self - retracting blade on a utility knife automatically retracts when not in use, minimizing the risk of accidental cuts. Folding blades still expose the blade when open, replaceable blades don't inherently have a safety feature related to reducing exposure when not in use, and plastic blades are not typically the main consideration for the "safest" utility knife in terms of blade type for safety during use (they are more about non - cutting or specialized uses). So the safest utility knife has a self - retracting blade.

Answer:

A. self - retracting
