Wholesale ABS Handle Tungsten steel Ceramic 2-Stage Knife Sharpener Kitchen Knife Sharpener

A 2-stage knife sharpener restores and maintains sharp edges through a two-step process. The first stage uses coarse tungsten steel rods to grind dull blades, and the second stage uses fine ceramic rods to refine and polish the edge. This system keeps knives and tools sharp and ready for consistent performance.

RTI’s 2-Stage Knife Sharpener uses tungsten steel and ceramic elements to deliver precise sharpening. The coarse and fine options allow users to adjust edge finishing based on the tool. The large ergonomic handle offers a firm grip in wet or slippery conditions, and the structure resists wear during outdoor and fishing use.

Product Specifications

2-Stage Knife Sharpener Product Details

Ergonomic Handle with Finger Positions

The large handle is designed with finger positions for a secure, comfortable grip, even when handling in wet or slippery conditions. It ensures safe sharpening for both novices and professionals.

Dual Sharpening Stages with Pre-set Angles

Features two sets of sharpening rods—coarse tungsten steel for restoring dull blades and fine ceramic rods for polishing and refining edges to perfection.

Coarse Tungsten Steel Rods

The tungsten rods quickly restore even the dullest blades with just a few strokes, making it easy to get back to work fast.

Fine Ceramic Rods

The ceramic rods refine and polish the edge, ensuring your blades are razor-sharp and ready for precision tasks.

Non-slip Rubber Base

The sharpener is equipped with a rubber base to prevent slipping while sharpening, providing stability during use.

Hook Sharpening File Included

Includes a hook sharpening file, making it versatile for sharpening hooks, knives, and other tools in your fishing kit.

2-Stage Knife Sharpener Manufacturing Process

1. Material Selection

We choose ABS for the handle, tungsten steel for coarse sharpening, and ceramic for fine honing. We source materials that meet strength and performance requirements.

2. Injection Molding of Handle

We inject ABS into precision molds under controlled pressure. We set the mold temperature at 180°C and adjust cooling time to achieve uniform structure and accuracy.

3. Tungsten Steel Rod Cutting

We cut tungsten rods to length with CNC lathes. We shape the rods to coarse grit using grinding equipment and verify consistent size and surface texture.

4. Ceramic Rod Cutting & Calibration

We cut ceramic rods using diamond-coated cutting wheels. We measure length, diameter, and grit with automated inspection tools to confirm uniformity.

5. Rod Fitting and Alignment

We insert tungsten and ceramic rods into the handle using alignment fixtures. We set the sharpening angle to 20 degrees to ensure correct positioning.

6. Handle Assembly

We secure the rods inside the handle using adhesive and mechanical fasteners. We use automated tools to maintain alignment and structural integrity.

7. Non-Slip Base Attachment

We mold a rubber base and attach it to the handle using compression molding equipment. We confirm the base provides stable contact during sharpening.

8. Quality Control

We test sharpening performance using metal sheet cutting tests. We check ergonomics by grip evaluation and run durability tests with vibration and temperature cycling.

9. Final Assembly

We inspect each sharpener for surface defects and structural issues. We remove any unit that does not meet standards and prepare compliant units for packing.

10. Packaging

We pack sharpeners in PVC bags or blister packs. We test packaging for drop resistance and transport protection. We provide custom packaging when needed.

11. Shipping

We arrange shipment through logistics partners and assign tracking based on order volume. We coordinate delivery time according to destination requirements.
