For the dentist who likes the efficiency of the Fine-Cut files designed into a hand file, these files are ideal for supplementing contra angle technique or for solo use.
Internally there is a precision ball bearing that allows the end to spin on its long axis while the distal end is hand held.
The file is laid flat on a sheet or rubber or thick paper and flexed upward while the end of the Curving Tool is rolled toward the end.
To curve a needle, the rotating end of the Curving Tool is pressed against it and the needle pulled upward and away from the tool.
Since it is all stainless steel, with a little maintenance and a little sip of oil once in a while it should outlast most dentists who use it.
