Knew Concepts Solid Brass Guillotine Clamp with Wood-Lined Jaws – 500.100

Hold small jewelry components securely while sawing, piercing, filing, and performing detailed bench work with this solid brass guillotine clamp from Knew Concepts. Designed to reduce the strain of gripping tiny workpieces by hand, this compact clamp provides a convenient way to stabilize delicate parts while keeping your fingers free to guide your tools.

The clamp features two solid brass jaws lined with soft, non-marring wood. These protective liners help grip jewelry components without the direct metal-to-metal contact of traditional clamps, reducing the risk of scratches and unwanted marks on the workpiece.

Two parallel threaded posts and adjustable nuts allow the jaws to open and close around small parts. Once adjusted, the clamp holds the workpiece securely so you can concentrate on precise sawing, filing, and piercing operations.

Its slim, flat profile makes it especially useful for tasks that can be awkward with a traditional ring clamp.

Manufactured in the USA by Knew Concepts, this guillotine-style clamp brings a traditional jewelry bench tool into modern metalsmithing applications.

Specifications

What Is a Guillotine Clamp?

A guillotine clamp is a compact holding tool designed to secure small workpieces between two adjustable jaws.

Unlike pliers, which require continuous hand pressure, a guillotine clamp uses a mechanical adjustment system to maintain its grip.

This allows the user to concentrate on sawing, piercing, filing, or other detailed operations without constantly squeezing the workpiece.

Knew Concepts has adapted this traditional bench tool for modern jewelry fabrication and precision metalworking.

Solid Brass Construction

The clamp's solid brass jaws provide a sturdy structure for holding small parts during detailed bench work.

Brass is a useful material for jewelry tools because it is softer than many hardened steel tools and can be less aggressive when accidental contact occurs.

The brass body supports the adjustable clamping mechanism while maintaining a compact profile.

The wood liners provide the primary contact surfaces against the workpiece.

Protective Wood-Lined Jaws

Both clamping jaws are lined with soft wood to help protect delicate components.

The wooden surfaces provide a gentler grip than bare metal jaws, making the clamp useful when working with finished or easily marked materials.

This is especially beneficial when holding jewelry components that require careful filing or piercing.

Although the liners help reduce surface damage, excessive clamping pressure or debris trapped against the workpiece can still leave marks.

For delicate finishes, use only the pressure necessary to hold the item securely.

Adjustable Threaded-Post Design

The clamp features two parallel threaded posts with adjustment nuts.

These allow the jaws to be positioned around the workpiece and tightened to hold it in place.

The adjustment system is useful when working with parts of different sizes and shapes.

Once the workpiece is secured, you can focus on guiding your saw or file rather than maintaining gripping pressure with your fingers.

Ideal for Piercing and Sawing

Precise piercing and sawing operations require a stable workpiece.

When a small component moves unexpectedly, it can make it difficult to follow a marked cutting line or maintain control of a jeweler's saw.

The guillotine clamp helps stabilize the component while providing access to the working area.

Its slim profile is particularly useful for operations where a bulkier clamp might obstruct tool movement.

Convenient for Filing Small Components

Small jewelry parts can be difficult to hold securely while filing.

The wood-lined jaws help support the workpiece without requiring constant finger pressure.

This makes the clamp useful for refining edges, smoothing small components, and performing detailed filing operations.

Always ensure the part is secure before beginning work, and avoid applying excessive force that could shift the workpiece or damage the liners.

Guillotine Clamp vs. Traditional Ring Clamp

Traditional wooden ring clamps are useful for holding many jewelry components, but their bulkier profiles may make certain detailed operations awkward.

The Knew Concepts guillotine clamp offers a flatter, more compact alternative.

Its adjustable threaded-post mechanism maintains clamping pressure without requiring the user to squeeze the tool.

The wood-lined jaws also help protect the workpiece.

Both tools have a place at the jewelry bench, but the guillotine clamp is particularly convenient for holding small, flat, or irregular components during precision work.

Ideal For

• Jewelry making and repair

• Metalsmithing

• Precision sawing

• Jewelry piercing

• Filing small components

• Holding delicate metal parts

• Working with jewelry findings

• Detailed bench fabrication

• Small-parts finishing

• Reducing hand strain during repetitive work

• Professional jewelry workshops

• Hobby jewelry making

Compact Design for Detailed Work

The clamp measures approximately 2-1/4 inches wide, 1/4 inch deep, and 2-1/8 inches high.

Its narrow profile makes it convenient for working close to the clamped component.

The maximum opening is approximately 1-3/4 inches wide by 3/4 inch high, allowing it to accommodate a variety of small jewelry parts.

Always confirm that the workpiece fits securely within the available opening before applying pressure.

How to Use the Guillotine Clamp

1. Inspect the clamp and wooden liners before use.

2. Loosen the adjustment nuts to open the jaws.

3. Position the jewelry component between the wood-lined surfaces.

4. Align the part so the area being worked remains accessible.

5. Tighten the adjustment nuts gradually and evenly.

6. Confirm that the component is secure before beginning work.

7. Perform the required sawing, piercing, or filing operation.

8. Loosen the adjustment nuts to release the workpiece.

9. Remove the component carefully.

10. Clean the clamp and inspect the wooden liners after use.

Avoid overtightening, particularly when working with soft metals or delicate finishes.

Proper Use and Care

• Keep the wooden liners clean and free of abrasive debris.

• Inspect the threaded posts and adjustment nuts periodically.

• Tighten the jaws evenly to maintain a stable grip.

• Avoid excessive force that could damage the workpiece or clamp.

• Do not use the clamp as a cutting tool.

• Keep the wooden liners away from open flames and excessive heat.

• Remove metal filings and debris after use.

• Store the clamp in a clean, dry location.

• Inspect the wood lining for wear before working with delicate surfaces.
