In this video I talk about some of the differences between a chisel ground ( or hand filed ) chain ....and a round ground ( or hand filed) chain.
There are pros and cons to both.
The biggest advantage to a chisel ground ( or hand filed ) chain is that it tends to hold its sharp cutting edge better and that is why most commercial timber fallers use chisel ground chain.
The biggest advantage to round filing is that it is a lot less of a learning curve and can be used successfully in many different cutting conditions.
It is probably the best option for cutting firewood, clearing brush, and can work pretty well in falling and bucking situations, but it will take more filing ( or grinding) then a chisel ground ( or filed) chain.
