How to practice Shuto in dojo without makiwara

This is how we practice shuto uchi in our dojo. We use woodboards as fokus pads. :) Usually folks practice shuto on boxing bag, but bag is too soft for shuto. Shuto is meant to break a bones and bones are not soft. We are using left overs from temashiwari for practice but any wood is good. Please dont practice on your doors because you will destroy it. :) If you try this go slow and dont push it – it is easy to get hurt.
