katar construction question

[P.Abrera]

I'm doing a bit of study on katar and I've been reading up on the older threads that discuss the various methods of construction, namely:

-solid 1-piece blade/handle

-separate blade & handle attached via a peened stub tang

-separate blade & handle riveted through the langets (usually firangi).

I'm interested to know the dimensions of the stub tangs on katars constructed with a separate blade and handle/stirrups? is there enough material there to make a solid battle-worthy weapon?

Can anyone share some measurements from quality examples?

Are there any examples that show evidence of more than one tang attaching the blade to the handle?

Thanks.
