I have a few Silky saws. They are insane sharp and fast. They cut on the pull stroke, and the blades tend to be on the thinner side. I broke a couple blades on the pocketboy 170mm models, so I think they are too flimsy for me. The Gomboy model is thinker and more robust. Of course they have even larger models if you need to cut bigger wood, and like to carry heavier saws.
For reference I also have a Bahco Laplander and it is very durable, but takes more effort for the same cut. It is also a good choice for light work.
