Review on 🔪 The Ultimate Sharpening Solution: Bora 501098 Combination Sharpening Silicon Unleashed! by Michael Custodio

The product shown is a silicon based copper stone. It is actually misidentified as silicon oxide. Silicon sharpening stones are silicon carbide and are preferred for harder materials like ceramic and glass, the latter of which I bought. Aluminum oxide works well for general sharpening of most metal blades and is less aggressive than silicon carbide stones. If I order an advertised product, I hope to receive that product or a product that matches its composition and application. I don't want a completely different replacement. Especially the ones that are cheaper. (Bora Portmate sells alumina bricks for less than half the price of silicon carbide bricks on their website.) Nothing wrong with alumina bricks other than that they're not what I wanted. I assume Bora thinks no one will notice the difference?
