A little something to add to both good ideas
Hoping not to offend pill head mold sales

Came a time when I was asked to make
about a dozen small jigs having 3D eyes
Well my grip isn't as strong as years past using pliers
hammered always came out somewhat uneven
having to be rehammerd
So came up with using flat jawed Vise grips
Which kept all the jigs in the same pattern
and easily adjusted for a different eye size

Hope this little hint helps for those with arthritic hands
