Over the years I have trained extensively in WadoRyu, Ishinryu, and more recently in Shotokan, for which I hold 4th Dan. I have always believed that a horizontal forearm is the sign of a weak block/strike and incorrect, in all three styles. I don't consider it a suitable block against a face punch but think it eminently suitable for a small person, like me at 5'4", to strike under the chin or jaw against a taller attacker. I don't believe it is a block, nor are any other strikes. In the past I was told it was suitable against a stick or baseball bat (if you want a broken arm). My respect to you, but you did ask for the opinions of others. If it is being taught as a horizontal block, then perhaps it is part of the mystery device philosophy. (my favourite video to date).
