In Australia you can get these from:
Search for codes E122B [blunt] and E122S [sharp].
In the UK http://www.fisher.co.uk/ have packs of 5 featherlight tweezers for
£18.10+VAT, but I think they only have the blunt type. Entomological suppliers
carry both types, usually priced at £4 to £5. So Simone's supplier in Germany
looks good value.
