Ok, my Lindstrom tweezers are now travelling to me.
In the meantime, thanks to eliocor's focussed attempts to corner the market on SM-100's, I am still looking for these.
If anyone can think of UK suppliers, that would be great. If not, any good supplier will do.
Update: Bahco rep just told me that SM-100 has been discontinued. If something like these is available from other good manufacturers, I'd appreciate your suggestions.
Update 7 Aug: Bahco catalogue lists Belzer tweezers, and one of these is quite similar to SM-100. Would anyone have anything to say for or against Belzer?
