Hi guys, I found this thread while looking online to buy a sjambok here in Australia. I'm originally from South Africa so I thought I'd add my 2 cents.
Quick review on the Cold Steel sjambok which I received a couple days ago:
I've had and used a sjambok pretty much all my life. Primary used for dispatching venomous snakes specifically, which there are many in Northern KZN. Taken out about 10 snakes with it. One of which was a one hit decapitation when a snake stuck his head out of a exterior drain line.
The CS sjambok is quite a bit heavier than your typical sjambok from SA, especially the handle. I've given it a good swing or two and feel slower with it than my standard sjambok made in SA. I wouldn't feel as comfortable with it confronting a snake as my wrist control would be affected. My wife is petite so I'm not so sure how she'll handle it.
Don't get me wrong, I do like it. It's really well made and feels more like a self defence weapon.
My sjambok in SA was thinner and easy to use. I think I took out my first snake around 12 years old. I don't think I wouldn't have been able to with the CS one.
So my recommendation is if you're looking for a self defense weapon the CS one is probably better, however if you're primarily going to use it to control snake population I would probably recommend one off bidorbuy.co.za (SA's eBay equivalent).
On side note, not one I'm proud of, but it may prove educational: When we were in our early teens my bigger, older brother and I got into a huge fight (he started it). He armed himself with a field hockey stick and I armed myself with the sjambok. The superior reach meant I won the exchange untouched with him getting a big ol cut above his eye. Obviously not a life or death situation but show me the damage it can do.
