Re: Kingfisher Bokken
We do several kumi tachi were you make contact and "slice" across your partner. Usually against the gi, but splinters are not welcome. Even without contact with skin, any loose piece of wood that can fly off is unwelcome.
I just replaced a splintery bujin bokken with a large enhanced aikiken from Kingfisher. I'm happy with my big heavy stick (compared to any bokken I've had) but have not yet used it in paired practice. The jo has held out well so far though.
