I am glad to see that Cookson have finally decided to stock these great saw frames. I was involved in a small way testing these saw frames for Lee Marshall when they were first introduced in 2009. Since I have used the Knew Concept saw frames I have found working long hours piercing a pleasure with the lightweight frames and their rigidity holding the saw blades firm and accurately inline. Lee uses photos of my test piercing item in his adverts and webpage. Some of the photos are shown below, it was a 5 inch diameter pierced silver overlay added to a guilloche enamelled silver bowl.
