What is the first meaning of たたき台?


たたき台 means a springboard for discussion.

According to my dictionary, this word's first meaning is "chopping block".

On [Google

it does not look like the plastic/wood board I use to cut meat/vegetables:

So what is the non-abstract meaning of たたき台?  
[ALC does not have
it](http://eow.alc.co.jp/search?q=%E3%81%9F%E3%81%9F%E3%81%8D%E5%8F%B0).




There are a lot of meanings related to たたき台 (as noted by the comments and
posts above.)

In one case (from your picture posted above,) たたき台 actually means something
like **"a pounding stand"** for baseball gloves. (Along with a たたき台, there is
also another tool used when pounding baseball gloves like this, called a たたき棒;
the actual glove-hitting tool.)

When you buy a typical baseball glove, it is usually made out of some sort of
leather. Leather usually requires some sort of maintenance from time to time
(and especially before a glove, in this case, is first used.)

One type of glove maintenance is the art of _"creating a pocket"_ so that a
baseball fielder can more-easily catch a fly-ball... or field a ground ball...
during a game of baseball.

The following (commercial) website describes what the process of _"creating a
pocket" can_ look like:

A tatakidai is quite literally a raised platform (台) that is hit / beat (叩く).
Usually it is used by retailers who beat it in an attempt to attract customers
while they shout out gradually reducing prices. Hence there is a sense of sale
associated with it.
