Hi Bryan, should think that's a record, he would have had 24 !!! very basic kit, questionable some of the homemade tool, the back of the ring tool cuts just as well as both sides of the ring cutter.
Have seen this guy before with a box or lidded jar, in that one it's straight out of the workshop into the front room/kitchen, cats/dogs and all the rest.
Well done on finding it. David
