SCOTTCHEN Diamond Flattening Plate – Double-Sided Lapping Stone, 10x3 in, 120/180 Grit

Overview

The SCOTTCHEN Diamond Flattening Plate is a precision tool designed to restore flatness to sharpening surfaces while supporting edge work on a range of blades and tools. Measuring 10 inches long by 2-11/16 inches wide with a slim 3/8 inch profile, this plate offers a sturdy, true bed for flattening whetstones, oilstones, and waterstones. Its dual-sided diamond surface (120 and 180 grit) enables smooth re-leveling and controlled finishing, making it a practical addition for workshops that demand consistent planarity during maintenance tasks on axes, hatchets, machetes, spades, and shears.

Two-Sided Versatility

The two grit sides are designed for distinct tasks, giving you flexibility without swapping tools. The 120 grit side helps establish a flat base quickly, while the 180 grit side provides a finer finish to maintain crisp edges. This makes it suitable for both re-leveling stones and performing precise re-bevel actions on edge tools.

• Flat and re-level whetstones, oilstones, and waterstones for consistent performance
• Re-bevel edges on tools such as hatchets, axes, machetes, spades, and shears
• Large working surface supports bigger stones and blades with stability
• Two grit options enable both aggressive flattening and finishing refinements

Wet or Dry — A Flexible Work Flow

This precision plate works in both dry and wet conditions, giving you room to adapt to your sharpening routine. After wet grinding, remember to dry the plate to help prevent rust and maintain long-term performance.

• Use with water or oil-based lubricants as your stones require
• Dry thoroughly after use to minimize corrosion risk
• Easy to clean and store flat when not in use
