Once there was the Miller dowel, now we have the Mirko Domino or Mirkomino! Awesome. Makes me wonder what might be the result if Mirko dominos were used in those joint tests. If the proportions were right, fracturing of the wood piece housing the cross-grain mortice (the stiles and table legs commonly) should require a higher load.
Mirko, what do you plan to use them for?
