Re- the links I posted earlier - I ordered both as a test on the basis that you can never have too many good pairs of scissors! I have now received both pairs and have done some chomping of [scrap] etchings.
The Friskar ones that Richard ordered are excellent indeed. Narrow blade width, very sharp and with good leverage. No further cleaning up of the parts I cut out was required. 10/10.
As an aside we have been using a larger set of Friskar scissors here for card & material cutting for 24 years and they are still going strong and are relatively sharp.
The Tim Holtz scissors are beautifully made but the blades are too wide really and the serrations [very fine as Graham says] do tend to 'pull' the cut into the brass and twice caused me to cut further into the part than just the tag - and would have ruined the parts on a good etched sheet. They are serious quality scissors but I would NOT recommend them for cutting out etched parts.
Of course the ultmate would be to have the Friskar scissors with the luxurious Tim Holtz handles fitted!
Hope the above is helpful,
