TYROLIT 89A FEIN sharpening stone - part 1

400 grit aluminium oxide sharpening stone made by Tyrolit. Ceramic binder with medium to high strength relatively hard stone does not absorb a lot of water does not load up easily easy to clean under running water or with spray bottle works pretty fast with 3Cr13 type of steels leaves noticeable coarse finish here in Bulgaria - around 20$ It will be very interesting how will it works with higher carbide steels like D2, CPM S30V etc. ==================== Faceoff by Kevin MacLeod is licensed under a Creative Commons Attribution license (https://creativecommons.org/licenses/...)
