You wouldn't catch me under a car supported by those contraptions. I
use, and will continue to use solid blocks of wood.
And to your point, why bother with them when there are other safer options.
Which way is the grain oriented? Using a piece of log, upright the
way it grows, is NOT a safe stand for most applications. Building a
pilon of stacked 4x4 "logs" is - but it's clumsy

I'm not convinced any other jack stand design is any safer

I don't know what Derby does, but those guys who break a board with a
karate chop have the board oriented 90^ from the way it looks. People
are used to the grain running parallel to the long side of a board,
which makes it hard to break a board, but when they do it, the grain is
parallel to the short side. People look at the wood and think
otherwise, so the guy looks amazingly powerful. I find this all sort
of annoying.

I'm not quite why I'm mentioned here. I never said anything about wood or
grain patterns or karate chops. You may have me confused with someone else.
