Hi ! this is Manish , like see i also had the same problem too which you are having , so i tried in many ways one you can do is use* acid* but that may be very dangerous , so instead *you can use the fire up technique* in which you can heat up the blunt blade to a very hingh temperature and then rub it against a hard plain surface which will make it sharpen (*/_THIS IS ONLY FOR ADULTS KIDS DO NOT TRY THIS_/* !!!)

I've found, in most cases, that the apparent dullnes is caused by a
build up of adhesive along the cutting edge. This can usually be removed with a petrolium base solvent. Another approach would be to touch up the cutting edge by deepening the notches in the metal cutting strip with a fine sharp cornered needle file or a dremel cutting wheel. |
