"I can't say I do. Michonne does." He'd had to learn how to fight with a number of things a time before walkers didn't require. Even with his police training, improvising to stay alive fell quickly into his repertoire of skills. Rick could swing an axe, knife, or machete well enough, and his aim with just about anything was about as on point as you could get.
The former deputy moved back around his desk to take a seat now that the conversation had grown lighter, he didn't feel the need to be so formal, stiff. "Lookin' for a sparring partner? I'm sure she'd love to match swords with someone willing."
That could have been just a guess though. Rick couldn't say for certain if Michonne would rather use her sword for protection or recreation. He'd never really asked about it.
