Peter Marker is one of those great knifemakers from Australia. He concentrates on folding knives and they run from big and bad to small and easy to hide. His knives are sharp and stand up to heavy use. Most use 440c as the blade material but he also works in Damascus and other metals.
Here are two from Peter. They are both his Maxi model. In the first picture you can see his knife between a large #4 folder from Kit Carson and a left hander from Robert Terzuola.
You can see more of his knives at his website...
