【CHEAP OPTION】 If your "old man" is feeling overwhelmed, use the chainsaw sharpener to sharpen his saw chains instead of throwing them away/replacing them. It's a job that requires patience, and when your "old man" is ready, you'll love him even more. A manual sharpener works just like a pencil sharpener. When sharpening a saw chain with a chain sharpener, place the clip on the bar, place the locking pawl on the tooth, insert the alarm into the guide sleeve, and turn the handle. Cleaning shiny chains in just 3-5 seconds is quick and easy. 【Excellent Chainsaw Accessories】 The chain grinder is made of aluminum alloy and stainless steel, which has strong corrosion resistance, pressure resistance and durability. 【Lightweight and Portable】 The size of the chainsaw sharpener is only 98.09mm * 65.32mm * 75.06mm, the chainsaw sharpener can be easily put in your pocket or small outer pocket, very convenient. 【Improved Design】 The chainsaw sharpener is equipped with 2 grinding holes with an angle of 30°, the left is a fixed hole and the right is an elastic hole, which can be moved back and forth to meet different types of hole chains. Comes with 3 chainsaw files, perfect for lumberjacks and gardeners who use chainsaw sharpening tools.
