TomE Report post Posted July 17, 2023 Rediscovered an iSTOR Swiss sharpener among my stones and hones. https://www.istorsharpener.ch/instructions-for-use/instructions-for-standard-professional-sharpener/ I was surprised how nicely it put an edge on a dull hoof knife that was ready to go after stropping. Thinking about using it on some leather tools to re-profile the blade. Does anyone have experience with the iSTOR sharpener? Quote Share this post Link to post Share on other sites
