The HONGDUI HD-34 Pro is a definitive sharpening solution for woodworkers who refuse to compromise on blade geometry. Engineered with a sophisticated self-centering clamping mechanism, this jig ensures that your chisels and plane irons are perfectly squared every time. The HD-34 Pro provides the rigid foundation needed for high-grit honing. Whether you are restoring a vintage blade or maintaining a premium tool, the HD-34 Pro delivers a razor-sharp, repeatable edge with professional-grade efficiency.
The HONGDUI HD34 Pro is a complete sharpening jig system for creating smooth, repeatable bevels on woodworking chisels and plane irons. Its angle fixture, dual-rail positioning system and stable brass rollers take the guesswork out of sharpening for professional woodworkers and DIY workshops.
Complete sharpening system
The kit includes a precision honing guide, angle fixture, 15°–47° angle gauge, two replacement brass rollers and a magnetic hex key. Whetstones are not included.
Repeatable 15°–47° bevel angles
A built-in positioning block locks in the selected sharpening angle, while parallel dual rails provide fast, accurate blade setup. This helps you reproduce consistent bevels without relying on repeated manual measurements.
Secure anti-slip blade clamping
The ergonomic knob and metal stud lock hold the chisel or plane blade firmly during sharpening. The stable clamping design reduces unwanted movement and gives you better control over each pass.
Stable dual brass rollers
Two brass rollers can be installed inboard or outboard to suit different blade sizes. The dual-roller design improves balance and helps maintain an even bevel angle. Two concealed spare rollers are included for convenient replacement.
Durable aluminum construction
The aluminum body provides strength and corrosion resistance for regular workshop use. The jig accommodates chisels and plane irons from 0.1 to 3.2 inches wide, making it a versatile sharpening solution for a range of woodworking hand tools.

FAQ
Check out the most common questions our customers asked.
What materials are used in the HD34 Pro?
The system is constructed from CNC-machined aluminum alloy and hardened stainless steel. This combination provides the necessary weight for stability while ensuring the tool remains rust-resistant, which is critical for wet sharpening environments.
What makes the Pro version different from standard honing guides?
The HD34 Pro features a modular clamping system and an integrated angle-setting jig. Unlike simple clip-on guides, the HD34 Pro ensures the tool is held perfectly square to the stone through a reinforced bridge structure that eliminates lateral flex.
What is the clamping capacity of the HD34 Pro?
The system is designed to handle a wide range of tools, from narrow 3mm (1/8 Inch) chisels to wide 65mm (2-1/2 Inch) plane irons. The reversible jaw design allows it to securely grip both flat-ground and tapered (Japanese-style) tools.
How do I set the sharpening angle accurately?
The HD34 Pro utilizes a stepped angle-setting block. By sliding the tool forward until it hits the specific stop for your desired angle (e.g., 25°, 30°, or 35°), you lock in the exact projection length required. This eliminates the need for manual measurements or external plastic gauges.
Can I create micro-bevels with this system?
Yes. The HD34 Pro is equipped with a micro-adjustment roller. By turning the eccentric dial on the roller assembly, you can increase the sharpening angle by approximately 1° to 2° without removing the tool from the guide. This allows you to hone a secondary bevel in seconds.
How do I ensure my chisel is perfectly square to the guide?
The guide features a self-centering clamping mechanism. As you tighten the knurled brass knobs, the jaws apply equal pressure from both sides, automatically squaring the tool's shank to the axis of the sharpening roller.
Is the roller compatible with all types of sharpening stones?
The HD34 Pro features a wide, stable stainless steel roller that works perfectly on water stones, oil stones, and diamond plates. Its width prevents the rocking motion that can cause rounded edges on your tools.
Does it support sharpening short blades?
Yes. The modular design allows the clamping head to be positioned closer to the roller for specialized or butt chisels that have shorter shanks.
Can I use this for Back-Flattening?
While the HD34 Pro is primarily a honing guide for bevels, its stable reference surface can assist in keeping a tool flat, though most woodworkers prefer to flatten the backs of chisels manually on a stone.
How do I prevent the roller from seizing?
After every sharpening session, rinse the guide under clean water to remove abrasive slurry. Dry it thoroughly and apply a drop of light machine oil or a dry PTFE lubricant to the roller axle and the threaded clamping screws.
Will the aluminum body corrode over time?
The aluminum is anodized to provide a hard, protective surface. However, long-term exposure to water—especially if left sitting in a sharpening pond—can eventually affect the finish. Always store the tool dry.
How do I maintain the accuracy of the angle-setting block?
Ensure no sawdust or metal filings accumulate in the "steps" of the setting jig. Even a small piece of debris can change the projection length and result in an incorrect sharpening angle.
