Hi Ahmed,
You are allowed to make your own blade. It just needs to be mainly made of wood. Here is the rule:
| 2.04.02 | At least 85% of the blade by thickness shall be of natural wood; an adhesive layer within the blade may be reinforced with fibrous material such as carbon fibre, glass fibre or compressed paper, but shall not be thicker than 7.5% of the total thickness or 0.35mm, whichever is the smaller. |

There is no perfect thickness, just what feels comfortable for you.
The type of wood else effects the feel of the bat.

In reference to the following rule, how do the officials test the blade to prove that it is 85% natural wood. How would they know if the blade was made of a higher percentage carbon fiber? This question was raised at our club, and I suggested that a non destructive way to do this would be to use a spectrometer, but I doubt that this is used. do you know what the procedure is?

I guess no manufacturer would risk to mass produce a blade that wouldn't comply with this regulation, but if the test is only visual, for a top player custom made blade it would be easy to hide a thicker layer of composite material by just not making it expand to the contour of the blade... Maybe they randomly sample a bat here and there from a tournament winning player and tear it apart?
(they're not like us, they're sponsored, they wouldn't care...)

@Deighton, Great point... and Jean... come on
...tear it apart...
The thing is that it really doesn't make enough difference for players to want to cheat on this.
