Precision double burnishers

Here you will find the "precision" burnishers double ended. Start by selecting a handle, then 2 stones. It's not a good idea than select 2 same shapes. Each handle is available with 2 types of stones (agate or hematite) and 7 stone shapes. 

- classic conical shape

- classic pointed cone shape

- pointed cone "flat end" (mainly to produce white lines in mezzotint)

- pointed cone "truncated 1mm" or "truncated 2mm". The flat truncated part allows to have a good polishing surface and a polishing without wave or irregular line, while being precise. Less natural to use than the curved shape. Perfect for accurate correction and gradients.

- curved shapes (thin in agate, medium agate or hematite, or large in hematite). Very comfortable and natural shape to use, easy polishing. For correction and gradients. For ergonomic, I think short handles are preferable (available here)

 On a metal plate, hematite gives the feeling of less slipping and being softer than agate. It seems that in printing, one can get better whites with hematite than agate. But hematite is more brittle than agate.
