i found that school in a town near me and i wanted to share the videos of their training.

for now i found those two videos one for dagger training and another for the sword and bucker (1:33?)

for those who actually practice this kind of martial art please tell me if it would worth it to study there even though the lessons are only once a week the sunday (at least the winter the lessons cost 60$ for 3 months and it is free for the rest of the year).

That is a negligible cost to cover indoor training, in what looks like a good space for a small group. Meet them and see if you like their attitude toward training. No harm in that.

Perhaps Maxime Chouinard will have further knowledge of them, he seems to be well connected in the Quebec historical martial arts scene.
