Knew Concepts 5" Titanium Birdcage Fret Saw – Lever Tension & Swivel Clamps

Experience exceptional rigidity, greater cutting reach, and precise blade control with the Knew Concepts 5" Titanium Birdcage Fret Saw. Designed for jewelers, metalsmiths, model makers, woodworkers, and precision craftspeople, this premium saw combines a distinctive titanium birdcage frame with lever tensioning and swivel blade clamps for outstanding control during intricate sawing and piercing.

The 5-inch throat depth provides generous working clearance for larger pieces and deeper interior cuts, while the titanium birdcage construction creates a remarkably stiff and stable frame. Greater frame rigidity helps maintain consistent blade tension and provides a responsive feel when following fine lines, navigating curves, and working through detailed patterns.

The lever-tension system makes repetitive blade changes quick and convenient, particularly when piercing designs with multiple interior openings. Swivel blade clamps provide additional flexibility by allowing the blade direction to change relative to the frame, helping you position the saw around larger or awkwardly shaped workpieces.

At 187.5 grams with the blade installed, the 5" Titanium Birdcage combines substantial rigidity, greater working reach, and excellent maneuverability for precision sawing.

Specifications

Titanium Birdcage Construction

The defining feature of the 125.005T is its titanium birdcage frame.

Knew Concepts developed the birdcage structure specifically to take advantage of titanium's properties while creating a highly rigid frame. The truss-like design uses triangulation to increase stiffness and stability while controlling unnecessary weight.

That rigidity is particularly valuable during precision sawing. A stable frame provides a firm platform for the blade, helping the saw feel responsive and controlled when making detailed cuts.

For jewelers and craftspeople working with valuable materials or intricate designs, that combination of rigidity and control is one of the strongest reasons to move up to the Titanium Birdcage series.

5" Throat for Greater Reach

The 5-inch throat provides a useful balance between maneuverability and cutting capacity.

It gives you more working clearance than a compact 3" saw without moving all the way to the larger 8" frame.

The additional reach is useful for:

• Larger pendants
• Cuffs and bracelets
• Decorative sheet metal
• Larger pierced patterns
• Sculptural jewelry
• Wood inlay
• Model-making components
• Deeper interior cuts
• Precision fabrication

For users who regularly find a 3" frame too restrictive, the 5" Titanium Birdcage provides substantially more room while remaining manageable for detailed work.

Lever Tension for Faster Blade Changes

Intricate piercing can require dozens of blade changes as the blade is moved from one interior opening to another.

The lever-tension system makes this repetitive process faster and more convenient. Tension can be released to reposition the blade and then restored after the blade is secured again.

That makes the 125.005T particularly well suited to:

• Detailed jewelry piercing
• Decorative metal patterns
• Intricate interior cutouts
• Complex sheet-metal designs
• Wood inlay
• Model making
• Precision craft work

Swivel Blade Clamps

The swivel blade clamps add another important capability.

Changing the blade orientation relative to the frame lets you position the saw more conveniently around the workpiece. This is particularly useful when working with larger sheets or shapes where the back of a conventional fixed-blade frame can interfere with the material.

Rather than always forcing the workpiece to accommodate the frame, you have greater freedom to position the saw around the cut.

Built for Intricate Piercing

The combination of rigid titanium construction, lever tensioning, swivel clamps, and a 5" throat makes the 125.005T especially capable for complex pierced designs.

The rigid frame provides a stable foundation for the blade, the lever simplifies repetitive blade changes, and the swivel clamps provide more freedom in positioning the frame.

It's an excellent combination for detailed work where precision and control matter.

Rigid Titanium Construction with Manageable Weight

The Titanium Birdcage frame is designed to provide exceptional rigidity while keeping the saw comfortable and responsive at the bench.

Unlike the lighter aluminum Mk.III frame, the primary advantage of the Titanium Birdcage design is its increased stiffness and stability. This rigid construction provides a stable foundation for the blade during detailed sawing, helping the tool feel controlled and responsive through intricate curves and pierced patterns.

125.005CS vs. 125.005T

Both saws provide a 5" throat, lever tensioning, and swivel blade clamps, but their frame construction is different.

The 125.005CS uses the lightweight aluminum Mk.III frame and weighs 148.3 g with blade. The 125.005T uses the rigid Titanium Birdcage frame and weighs 187.5 g with blade.

The aluminum Mk.III emphasizes minimum weight and maneuverability, while the Titanium Birdcage design emphasizes increased frame rigidity and stability during precision cutting.

The Titanium Birdcage is not the lighter choice. It is designed for users who place greater value on frame rigidity and stability. 

3" vs. 5" Titanium Birdcage

The Titanium Birdcage series is available in different throat depths to accommodate different sizes of work.

125.003T – 3" Titanium Birdcage
Compact and maneuverable for smaller precision work.

125.005T – 5" Titanium Birdcage
Adds two inches of throat depth for larger workpieces and deeper cuts.

The 3" model weighs 171.5 g and the 5" model weighs 187.5 g, so the additional two inches of throat depth adds only about 16 grams.

Frequently Asked Questions

What is the Knew Concepts 125.005T?
It is the 5" Titanium Birdcage Hand Saw with Lever Tension and Swivel Blade Clamps.

What is special about the Titanium Birdcage frame?
The birdcage design uses a titanium truss structure developed to provide exceptional stiffness and stability while controlling weight.

How deep is the saw frame?
The 125.005T has a 5-inch throat depth, providing more reach than the 3" Titanium Birdcage model.

Does this saw have lever tension?
Yes. The 125.005T combines lever tension with swivel blade clamps.

Why are swivel blade clamps useful?
They allow you to change the blade direction relative to the frame, giving you greater flexibility when the frame would otherwise interfere with a larger or awkwardly shaped workpiece.

Is it good for piercing?
Yes. The combination of a rigid frame and lever tensioning makes it particularly well suited to detailed projects involving repeated interior cuts.

How much does the saw weigh?

The 125.005T weighs 187.5 grams with the blade installed, approximately 6.6 oz.

Is the titanium model lighter than the Mk.III aluminum version?
No. The 125.005CS weighs 148.3 g, while the Titanium Birdcage 125.005T weighs 187.5 g. The titanium model's key advantage is greater frame rigidity, not simply lower weight.
