USPS came through again today, this time from Ofrei (cheapest around for these after much looking). Thanks JAWS for the recommendation and answering all my questions on these
New Horotec tweezer for removing spring bars. Horotec watchmaker’s tweezers are 100% anti-magnetic Inox and have been sand blasted to a smooth, non-glare finish. The tips are polished to a precision, mirror-like finish. Designed to insert/remove double shoulder and double flange spring bars with one easy sqeeze of the tweezer. Not for use on single shoulder spring bars. Length: 120 mm.
Haven't used them yet. Also bought some high quality 20 & 22mm Swiss spring bars.
