Knew Concepts Coping Saws & Fret Saws for Precision Hand Cutting

Knew Concepts redesigned the traditional coping saw and fret saw from the ground up, replacing the standard steel bow with lightweight, rigid aircraft-grade aluminum frames that maintain precise blade tension throughout the cut. The result is a hand saw that cuts with far greater accuracy and control than a standard coping saw, with minimal blade deflection even on tight-radius curves.

The Knew Concepts 6.5" heavy-duty coping saw is built for demanding work in hardwoods, laminates, and metals. The lever-tensioning system allows blade tension to be set and released quickly without tools, and the swivel blade holders allow you to rotate the blade to any angle — essential when cutting curves in the interior of a panel. The Knew Concepts fret saw offers the same precision in a deeper-throated frame, giving you greater reach from the edge of the workpiece for interior fretwork and intricate scrolling patterns.

Compatible Blades for Coping and Fret Work

Blade selection is critical to a clean cut. The Pegas 18 TPI coping saw blades sold alongside the Knew Concepts saws are Swiss-made, hardened-tooth blades that deliver extremely clean, smooth cuts in hardwoods and thin stock. The fine tooth pitch minimizes tear-out on the face side, making them ideal for joinery work, pattern cutting, and scrolling.

  • Aircraft-aluminum frames for rigid, vibration-free cutting
  • Lever-tensioning system for quick, tool-free blade changes
  • Swivel blade holders for any cutting angle
  • Compatible with standard pin-end coping saw and fret saw blades

Frequently Asked Questions

What makes Knew Concepts coping saws different from standard coping saws?

Knew Concepts frames are machined from aircraft-grade aluminum rather than bent steel tube. The rigid frame combined with a lever-tensioning system maintains significantly higher and more consistent blade tension, resulting in straighter, cleaner cuts with less blade drift and deflection.

What is the difference between a coping saw and a fret saw?

A coping saw has a shallower throat depth — typically 4–6" — and is used primarily for coping trim joints and cutting curves near the edge of stock. A fret saw like the Knew Concepts fret saw has a much deeper throat, allowing cuts further from the edge for intricate interior fretwork and scrollwork.

What blade size is compatible with the Knew Concepts 6.5" coping saw?

The Knew Concepts heavy-duty coping saw accepts standard 6.5" pin-end coping saw blades. The Pegas 18 TPI blades sold at Infinity Tools are a recommended match for fine, clean cutting.

What does TPI mean on saw blades, and which should I choose?

TPI stands for teeth per inch. Higher TPI (14–18+) leaves a smoother cut surface and is best for thin stock, hardwoods, and finish work. Lower TPI (10–12) cuts faster and is better suited for thicker stock or rougher cuts where speed matters more than surface quality.

Can the Knew Concepts coping saw blade be rotated to cut in any direction?

Yes. Both the coping saw and fret saw feature swivel blade holders that allow the blade to be set at any angle relative to the frame. This is essential for cutting curves that change direction, such as interior cutouts or complex scrolled patterns.

Is the Knew Concepts fret saw suitable for beginners?

Yes. The rigid frame and consistent blade tension actually make Knew Concepts saws easier to control than inexpensive alternatives, which can frustrate beginners with blade wandering. The swivel blade and lever tensioner also simplify blade changes and angle adjustments.

What materials can be cut with Knew Concepts saws?

With the appropriate blade, Knew Concepts coping and fret saws cut hardwoods, softwoods, plywood, MDF, laminates, plastics, and even thin metals. Blade tooth pitch and material determine the appropriate TPI choice.

Does Infinity Tools carry replacement blades for Knew Concepts saws?

Yes. Infinity Tools carries Pegas 18 TPI coping saw blades, which are a high-quality Swiss-made blade compatible with the Knew Concepts coping saw.
