If indeed it is a blurb, then I would save it for the part on the application where it asks about hand-eye coordination. Personally, I had a lot to say in my PS and I felt that hand-eye stuff was not vital. Truthfully, I can't see someone's application being make or break based on hand-eye skills but that's just my opinion (I assume that they just want to see that there are some skills available). If you can tie it in as being important to 'you being you' and if it will make your PS stronger then feel free. IMHO.
