Differnce between webmaster tools inbound links and google

Ok, heres something I cant work out, maybe someone else can.

If I do a google search for link:voodoochilli.net I get about 56 inbounds links showing up as far is google is concerned. 56 isnt very good and I am sure that its more than that.

Now in my google webmaster tools, it shows about 1600 inbound links (Thats more like it!). I have checked some of these links displayed and they are valid. Now there are some duplicates in the sense that 1 site might have links from several differnt pages.

Which one should I pay attention to? Is it 56 links or 1600? quite a differnce! why does google show me 2 different results??
