𝐃𝐮𝐫𝐚𝐛𝐥𝐞 𝐌𝐨𝐧𝐨𝐜𝐫𝐲𝐬𝐭𝐚𝐥𝐥𝐢𝐧𝐞 𝐃𝐢𝐚𝐦𝐨𝐧𝐝: Exhibits superior structural integrity and fracture toughness, ensuring long-lasting performance and consistent sharpening under heavy sharpening pressure.

𝐀𝐝𝐯𝐚𝐧𝐜𝐞𝐝 𝐄𝐥𝐞𝐜𝐭𝐫𝐨𝐩𝐥𝐚𝐭𝐢𝐧𝐠 𝐟𝐨𝐫 𝐋𝐨𝐧𝐠𝐞𝐯𝐢𝐭𝐲: The advanced Three-Times Electroplating Process firmly anchors diamond particles and precisely controls abrasive exposure—ensuring long-lasting, consistently sharp cutting surfaces.

𝐌𝐢𝐫𝐫𝐨𝐫𝐅𝐥𝐚𝐭 𝐓𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲 𝐟𝐨𝐫 𝐀𝐜𝐜𝐮𝐫𝐚𝐜𝐲: MirrorFlat technology with precision-ground flatness (±0.002 inch / 0.05 mm) ensures even blade contact for accurate edge geometry and consistent sharpening results.

Easy To Operate: First, find out the chisel’s bevel angle with the angle gauge. Then lock the positioning block at the same angle on fixture. Place the chisel sharpening jig on fixture and adjust the knob at either side to make opening larger. Then insert the blade and make the blade tip contact the groove on the positioning block. Tighten the screw to fix the blade. Finally, Start rolling the chisel honing jig back and forth on the whetstone

Built To Last: Mainly crafted from anodized solid CNC-machined aluminum alloy and stainless steel material, this chisel honing guide is rustproof, corrosion-resistant, and durable.
