【 Budget Option 】 If your “old man” is feeling too tired, sharpen his chains with a chainsaw sharpener instead of throwing them away/replacing them. It's a job that requires patience and you'll love your age even more when finished. 【Chainsaw Chain Sharpening Kit】The manual sharpener works like a pencil sharpener. When sharpening a chainsaw chain using a sharpener, place the clip on the shank, place the locking pawl on the teeth, insert the reamer into the guide sleeve and turn the handle. It only takes 3-5 seconds to clean the shiny chain, it's quick and easy. 【Great Chainsaw Accessory】 The chain grinder is made of aluminum alloy and stainless steel, which has strong corrosion resistance, pressure resistance and long service life. 【Lightweight and portable】The chain sharpener measures only 10 cm x 7.5 cm x 6.5 cm, the chainsaw chain sharpener fits easily into your clothes pocket or a small bag for the outdoors. Very practical. 【Upgraded design】The chain sharpener is equipped with 2 sanding holes with an angle of 30°, the left is a fixed hole and the right elastic hole can be moved forward back to fit different types of hole chains. Comes with 3 chainsaw files, perfect for loggers and gardeners who use chainsaw sharpening tools.
