Difference between a Klewang and Bangkung

[Spunjer]

how can you differenciate between the two? it seems to me that the blades looks exactly the same; if it wasn't for the handle, i can't tell the difference. case in point is zelbone's bangkung and a fine specimen on artzi's website. now let me throw in the t'boli kampilan aka toh. again, it seems like if it wasn't for the handle, i can't really tell the difference.

another thing: if the handle is bound with fiber, jute and/or rattan is it more or less a moro weapon? i've been wondering about this.

please discuss...
