FYI ...Mr. Mony does not retip. Infact nobody in India does retipping of stylii. What he does it replace the stylus with a unused one (meaning the cantilever + diamond/sapphire tip). I wanted to start retipping and asked for prices of diamond tips from Japan manufacturing company and quote I got was around $100 per diamond (for a lot of 300) for conical, elliptical, shibata and microlinear types. So I gave up the idea.
