Seamus,
There are two types of folks on this site those that do and say and those that say based on Google etc.
Keep saying I have your back as a WYSYGIG person myself and we both have others in mind, for ourself motives are I noticed out loud, no hidden agendas or just for the sake of.
This man sincerely ie Nikitas was sharing his best and I felt for him with his demo sort of like happens to me things drop etc.
Nikitas I feel sorry for those that market this product as well however the idea has been in production in the UK for umpteen years using high speed steel ground to shape. All of us are beneficiaries of third party manufacturers of the tips and present day Carbide micro fine grain tip manufacture.

Kind regards Peter.
