Description

Crown 240KW-10 mm Cryogenic scales guts. I use these scaling guts for the last cut when I finish my scales. The ' Cryo ' steel guarantees a sharp cut. The steel of the "Cryo" chisels of Crown hand tools from Sheffield in England has had an extreme heat/cold treatment which changed the structure of the steel. It has been given a longer stand-in period and a sharper cut can be applied to the chisel T. O. V the standard M2 HSS.  At first I was somewhat sceptical about these "cryo-chisels" but working with it convinced me! I always do the "Final Cut" at my scales with a cryo chisel. Trained Wood turners will notice the difference! The handles of these chisels are of "ebonized" ash wood and very long, so that they can be printed well against the body while rotating. More about the cryoniseren of steel can be found here. [Embed] https://www.youtube.com/watch? v = 4R3SN8fk1G4 & feature = Youtu. be [/embed]
