I haven't work hardened my Jo yet, I have a week till next practice and I think I'll have to consign myself to the shed for an evening so I can tap away without the dreaded Wife monster appearing
.
Seriously though, I really like the look of the Aiki Ken and I think I'll save up for the grade 7. I don't think I could afford the extra £100 for the enhanced version. I don't expect the Aiki Ken to never get any dents, but I'll look after it well so it should last me a long time.
Can you use any hard surface for work hardening? For example another Jo.
