KB4-NS / 3 contains three blades in a plastic box and a plastic bag. AK-4 scalpel blade Blade for very precise sawing
The blade has the shape of a narrow ball and is used to cut small pieces of wood and plastic. The teeth of the ball are turned towards the handle, which means that the cut occurs at the moment of pulling, not pushing the tool. Thanks to the use of tool steel with appropriately selected parameters and precise sharpening, the cutting blade was obtained easily, accurately and extremely durable.
