To use it you insert the brass cone into the borer, the blade is then brought forward to rest on the edge of the borer. Thumb pressure is applied to the back of the steel blade which when rotated sharpens the cutting edge of the cork borer.
Regarding this, are Cork Borers sharp?
A cork borer is a tool which is used to bore holes in corks (surprise!). We do not often use corks in apparatus, so it is more likely to be used to make the holes in rubber bungs. Cork borers come in sets of different diameters. The ends are fairly sharp for cutting purposes, so care has to be taken in use.
Secondly, how do you sterilize Cork borers?
Sterilize a cork borer by autoclaving or disinfect it by rising in alcohol followed by sterile water.
