Thanks to all forum members who contacted me both off and on line
regarding these burs. This really is a sharing community! I actually
have the Otto Frei Florentine burs. They produce a nice satin finish
but not the line pattern that my Rio one does. The cut on them is
different. At this point my bur is doing a good job so I really
don’t need a replacement. It doesn’t get heavy use so it should last
me well into my dotage! I’ve had it at least twenty five years and
at the time it was around $40. which is why I didn’t buy all three
sizes that were offered at the time.
I also have a ‘checkering’ file that produces a line pattern, just
not as deep as the bur. These produce an interesting finish, are
available in various cuts and are easy to use.
By the way, a while ago I actually found a bur manufacturing company
that offered multiple sizes of Florentine burs. Can’t remember the
name-not one I was familiar with. So I saved it to my favorites list
on my computer for future reference. Then my computer died and of
course that info didn’t transfer to my new one. Oh well.
