Poke them with the sharp end (Open to those he's teaching to spar + anyone who wants to learn)

Now that Ivar actually had a crop of people he was teaching, he'd had to make up a schedule on when he was seeing them. Fortunately, there wasn't enough to make it overwhelming for him to keep track. He'd arrive early at the training center so that he could put out a variety of weapons. Contrary to what his commercial might have lead people to believe, Ivar was talented in a number of weapons besides just knives and axes. He figured it wouldn't hurt any to get people using more than one as well.

Once someone arrived, he'd look them over with a critical eye as if he was silently saying, 'I've seen worse.'. While it mainly looked like he was judging them, he was really looking for which weapon he thought would suit them best. Once he had decided which was going to work out best, he'd select it from those he'd lined up.

"Alright, let's get started."
