Good afternoon KKellas,
Thank you for your email.
We can recommend silicon carbide ceramic sharpening stone available on the market. The stone should be dual-grit: coarse (120 grit) and fine (320 grit) sides. The coarse side is used for bringing dull edges back to sharpness. The fine side is used to restore edges that are slightly dull, and for refining the edge left by the coarse side.
