Compact precision you can carry

The TREND 3-Inch Double-Sided Diamond Sharpening Stone redefines on-the-go edge care. Sized like a credit card, this durable tool offers two grits in one slim card: a coarse 300 grit face for quick sharpening and a fine 600 grit face for honing. The combination lets you move from rough edge restoration to refined edge finishing without carrying multiple stones.

Built to last, the tool features industrial monocrystalline diamonds electroplated onto a steel base, delivering reliable performance across repeated sessions. It ships with a storage wallet, so you can stow it safely in a tool kit, pocket, or bag for travel between jobs, workshops, gardens, or kitchens.

• DOUBLE-SIDED DESIGN: Coarse 300 Grit for sharpening and Fine 600 Grit for honing, all in one compact card.
• CONVENIENT SIZE: Wallet-sized slab with an included storage wallet for portable sharpening anywhere.
• MULTIPURPOSE SHARPENER: Ideal for carbide and HSS tools such as router bits, chisels, blades, and carving tools.
• EASY TO USE: Apply light pressure to achieve a sharp edge; Trend Lapping Fluid is recommended to reduce clogging or rust (sold separately).
• NO NEED FOR MULTIPLE GRADES: Monocrystalline diamonds on both faces provide fast stock removal without extra stones.
