One of the guys at work just revealed that he was in an antique shop on the weekend and saw this boomerang on the shelf for a quid, so he snatched it up – being a bargain, of course.
In the cold hard light of post-euphoric analysis however, he's spotted a problem, and naturally has come to me – clearly the resident expert on the topic – for some advice.
He wanted to know if boomerangs were left or right handed.
(Incidentally, in following that up I was quite amazed at how many non-boomerang related articles came up in a google search for “boomerang”).
This page probably gives all the info you're ever likely to need. Assuming you're interested.
