I have seen mentioned several times here about people using the semi or full skip chains and have even seen them in the catalogs. I'm still at a loss when it comes to understanding their function and advantages. Most all my saw needs are for residential tree removals. No logging or milling. My #1 chain I use is a full chisel and I like it. This year I was going to try the semi-chisel or rounded corner teeth because I know they can take a little more beating when it comes to cutting dirty wood. I was going to use them for stumps, but then I see a chain that is partial tungsten/carbide treated, so I'll be using that instead for cutting stumps off low to the ground to prep for grinding. My question is: What are the skip chains functions and advantages over a chain I like to use, the full chisel? Are they suppose to cut faster? Be more durable? Cheaper? Do they have different tooth designs or do they primarily come in one style? If so, which one? Thanks, StihlRockin'
