Very good product and particularly useful for chain sharpening in the field. The biggest surprise is the quality of the round file. It cannot be compared to the no-name ones in the market, as you can tell by the sound when grinding the metal. I will be using these from now on. There are some negative points, which are not as important in terms of functionality of the set: The handle of the depth gauges is scratched by the square file during the filing process, which should not normally happen. The plastic measuring tool seems to be of average quality, especially considering that the white paint had not dried before the tool was placed inside its case, causing it to chip in some areas - more of a production process error than a material issue. Nevertheless, it is sufficient for the measurements it needs to make. The leather case seems good - definitely not for carrying on the belt, but inside a toolbox. If something is missing from the set, it would be the support handle for the blade (code 26368A), which supports the chainsaw in an upright position and allows for easier and more precise chain sharpening. The end result is a chain that cuts! I highly recommend it
