If anyone needs a decent tip to fit the Glanze blades, they are an ISCAR clone, GTN series.
Zenit (Italy) do a very good 2mm seat TiN coated tip for the smaller blades. Actually it has rather transformed the performance of he blade, having put up with the black cheapie.
You can get genuine ISCAR tips on Ebay quite cheaply – I was told not to be surprised if the source was Israel ….since thats where ISraeli CARbide make them!!!
