For the mastercut bowl gouges, Oneway has Cobalt added to the steel. This creates the steel Hamlet calls 2060 and Crown calls it Pro PM. It is a gouge that holds its sharpness extremely long. These gouges are delivered without a handle. That’s fine because in this way you can make yourself easily recognizable handles and don’t grab wrong. If these gouges are delivered they must first be sharpened. If you write me what kind of bevel you want to have on the gouge (in the “comments on your order” box) I can do it for you too. To clamp this guts into the OneWay chisel handle you need an adapter.
