Nothing is ever truly "blocked". It is either absorbed, redirected or dodged - or, a mixture of the above. To block, in a literal sense, means to stop - and the only true way to dead-end a horizontal one or two is to jam it completely - which would be akin to catching it in the early phase of the strike before it has reached its peak, or - offstepping the strike to catch it after peak phase - in which case you really haven't blocked it at all, rather -you allowed it to dissapate to a catchable speed. Nevertheless, you didn't block it at it's peak. To "block" it at its peak speed, hand-to-hand and stick-to-stick, would take near perfect timing - a luxury not usually granted in a full-contact stick match - good in practice, but seldom in fluid fighting.
My suggestion, having done, literally, hundreds of hours of full-contact stick fighting wearing riots helmets, fist gear, and utilizing a host of other full-speed contact gear and sticks, in realistic settings and training - while employed as a former special operations response team member, is this - you can learn the perfect block for not only these strikes but others as well, but don't bet your life on it -

I'd spend more time on striking harder and striking first.
