The old style of Planer Knives are becoming a thing of the past. They take too long to change and the cost of a grinding machine to sharpen the Knives can be very expensive.
The metal grindings are difficult to recycle so the old style Planer Knives aren't environmentally friendly.
The Tersa™ Planer Blades are two sided and are used on each side before they are recycled. They are ultra-light and don't need sharpening.
You simply use them twice and recycle the blade. No more WASTING valuable time on sharpening.
With the old corrugated blades it can take anywhere from 30 minutes/head to change a 4-sided Planer machine not to mention the sharpening time.
With Tersa™ ultra-light systems it takes just 5 minutes/head!
Because of their unique design Tersa™ Knives can also be changed in seconds. Used with the Tersa™ Planer Head, knives are clamped by centrifugal force and gibb wedges, leaving no screws to deal with.
