I have a couple of chainsaws,A 16" and a 14", and six chains. and I don't know jack about sharpening a chain so, to start out and try to hand sharpen them with files is and a probably not going to work out very good. But IDK I could give it a try I sharpen, my plane blades, chisels, jointer knives ,and such ,but never sharpened a chain saw chain. I have been reading on here in learning some things, anyway this is what I'm thinking. Purchase this ,Granberg Bar-Mount Chain Saw Sharpener, Model# G-106B , or the , HF Chain Saw Sharpener, or maybe both. I can get the HF grinder for 32 bucks with a 20% off coupon . The timberline chain sharpener looks like a good tool , but a rich price. What are your ideas, input, advice ???
