The Knight of Pentacles reversed is about feeling stuck in a routine and a repetitive pattern. Life is becoming boring, and you are beginning to long for change or any sort of spontaneity. To break free from this routine, try to do things differently each time and bring some spontaneity into your life.
In a relationship, the reversed Knight of Pentacles can indicate restlessness and apathy. One partner may be happy with routine but for the other partner it is tormenting. Your relationship might have lost its romantic side, and now you are focused on daily activities. Try to free up some time in the day to spend some quality time together or you might risk losing the attention of your partner.
This card can also suggest that recently you have chosen to ignore certain practical matters like money matters, taking care of the house; and have decided to focus on more important or exciting opportunities.
As a person, the Knight can represent someone who is way too conservative, cautious and change-averse. If this is you, you might be cutting off from others. Try to get out some more and remain open to new experiences and opportunities.
The reversed Knight of Pentacles can also suggest you are becoming a fault-finder regarding your work. You might be disapproving of others who are not as detail-oriented as you are, and thus, you may become frustrated when their work does not follow your standard. Although your hard work is valued, you surely do not want to lose the support of others; you might need to give some flexibility to your approach.
