"I brought this saw for logging some 30cm(ish) thick hardwood tree trunks (yes I should be using a chainsaw but I dont have one). It worked very well, way better than the bow saw I had brought previously. I have not made that many cuts so its hard to tell how long it will last but it certainly felt just as sharp as when new after several. Highly recommended based on my experience with it so far. Perhaps its a touch expensive, and the cut it makes is fairly rough, but thats fine for what I want it for."
