Today I struck mi first counterpunch. To leave a reasonable depression on the punch's surface took about 12 or more blows with a 3 kilos hammer. More than what I've expected And I had to place the vice on the floor because the table was making everything to bounce. In the end the counterpunch broke. Its tempering was obviously not well done (the straw color was not so close to the tip). Well, I've learned some lessons today.
