Four utensils go into my LBK for sanitizing:
First, a silicone spatula.
Second, a silicone whisk.
Third, a can opener that has no sharp edges.
Finally and potentially most dangerous, the kitchen shears I use to open the yeast packet and LME packets (If used). These are placed very carefully on top of the other utensils.
The LBK sits in a spot where there is practically zero probability of it being jostled and absolutely zero probability of it being dropped.
This method has served me faithfully through all my brews.
But you should do what makes you most comfortable. Making home brew shouldn't be stressful, so if you want to sanitize your utensils outside of the LBK, you should do so.
