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.

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.

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.

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.

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.

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.

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.

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.
