The Silky saw blades are expensive, thin and have a narrow kerf. What FortyTwoBlades said is correct, take it easy and let the saw do the work. Take it especially easy when pushing the saw blade back into the cut or snap! Been there and done that more than once.
I just looked at the Silky website. It's amazing the many ways you can configure each saw. You've got curved blades, straight blades, folding saws, fixed saws and most are available in different lengths and tooth configuration. I still prefer the Aluminum framed models which are a little lighter. All of the saws I have always have the largest teeth available. My favorite is still the Super Accel 210mm, straight blade, coarse teeth and aluminum frame. I like it better than the Pocketboy. I have seen the Gomboy...it would be my second choice even with the steel frame. I would again choose the coarsest teeth; it will still make a smooth cut. When the wife and I do trail maintenance we take a Stihl battery powered chainsaw and a large Silky Big Boy 2000 (about 14") curved model. We use the Silky as a backup if we get the chainsaw bar wedged (I have a spare bar at home, I don't carry it in the field).
One other thing...the saws are color coded. A particular saw with a certain type of tooth will have it's own color. For example the Pocketboy with large teeth is red. The one with medium teeth are black. I think my first Silky was a Pocketboy; I just bought it at the store, I didn't pay attention to the tooth configeration but I got the medium which was black. I lost it at some point and the next one had the large teeth and a bright red handle which was easier to find.
One more thing to think about...these saws are sharp and I can cut through a branch as big as my thumb easily with one pull. Earlier on I did cut myself, nothing bad and usually the hand or finger. I now wear leather gloves with cuffs to help out. The teeth in these things are like razors when new. I've wised up with the chainsaw also. I've got everything safety wise except some chaps which I will have by the end of the week. Help is a long ways when your in the middle of the woods bleeding to death.
