I myself make firewood for winter heating and campfires from raw logs, so I am particular about the quality, such as usability and sharpness. I personally use several blades from each lot to check the quality. The background to offering this product is that I felt it was a waste of time and effort to sharpen the blades, and I was looking for a high-quality, low-priced saw chain when I came across this product. I use it without feeling any particular stress compared to manufacturer products in terms of usability and sharpness, and I have received many similar comments from customers, so I am confident that you can use it with peace of mind. We highly recommend this product to those looking for affordable, high-quality saw chains. 【Product Specifications】 ・Pitch: 3/8 inch (approx. 9.5 mm) ・Gauge: 0.050 inch (approx. 1.3 mm) ・Drive Link Count: 52 ・Guide Bar Length: 14 inches (approx. 35 cm) We have received many bulk orders from professionals in forestry, agriculture, and landscaping.
