I have been hearing you asking for a metric Wrunt or Prybaby. Here's my problem...in order to maintain a neat and orderly stair step design in the wrench cut out area I can only do 2mm increments in size. That means you get either odd or even numbers. I know 10mm and 12mm are common sizes but there are odd ones as well that get used a lot.
Yes, I could do something weird like 7, 9, 10, 11, 12, 15 (making that list up since I don't use metric much) or something like that but it would look like crap. I really don't want to make a compromise on the design particularly so I want to avoid irregular steps. But if there are truly frequently used sizes in there I might reconsider.
So, give me your vote in the comments area for an odd or even scale. I do moderate the comments so just post once and I will eventually catch up with publishing them.
Not sure when a metric tool would happen but this is for research... ;)
