sharpening a curette

To get a strong edge - the outer and inner surfaces of the cup must be beveled 45 degrees towards each other- and must meet following the curve of the cup exactly-The indian curettes do not do too well - the Storz and the Spiggle &Theis curettes are very good for this treatment-The edge lasts for about 6 months - and will need sharpening again -and the storz curettes can be sharpened 4 - 5 times before they are discarded- Otolaryngoloy Update is now Please subscribe it by mail again as the old subscription will not work
