Review on 🔪 The Ultimate Sharpening Solution: Bora 501098 Combination Sharpening Silicon Unleashed! by Mike Morris

This stone works well as a sharpening stone for diamond saws. Also, at this price point, it's a lot cheaper than items specifically marked as diamond whetstones. The stone is silicon carbide (SiC), although the ad is unclear and the packaging says it's silicon oxide (which it isn't). The SiC stone has a grain size of 240 on one side and 320 on the other. Measurements in specs are accurate, other stones appear to be smaller. Overall, it's worth it for straightening diamond saw blades.
