The block - the mainstay of pretty much every Martial Art. Are they really so good, at least the in the classic sense of being blocks - meeting force with force?
Let's consider that almost all (maybe all) "blocks" as they are found in the kata are only defending movements as secondary or tertiary applications. I think we'll all agree on this. The head block can be used as a block but it has much better primary use. Instead reactionary defencive movements against strikes in kata are nearly always flinch responses.
Then consider the thread on x-blocks and my point that maybe "x-transition" is a better phrase. I mentioned Iain's take on stances that I never previously considered but wholeheartedly agree with and how the x-block is (or should be) essentially the same - a snapshot of a bigger movement.
I've heard one (Jujitsu) Sensei say that "block" is an outlawed word in his dojo. I personally teach flinch responses and body movement rather than meeting force with force. I do teach deflections.
With this in mind, does anyone teach "blocks" in their classic sense still? Are they worthwhile? Can they be wholly replaced? Is it another case, much like "stance" where it's not a great word to use, but we understand what is meant?
