84mm scissor springs

[stot]

I picked up a Salesman in need of a new scissor spring. A seller on Ebay lists a "Medium" spring that is supposed to fit 74 and 84mm. Is this correct? The knife is early 80's and I assume it originally used the wishbone type spring. Can any one guide me to the correct replacement.

Swissarmy.com is a bit slow answering my request.

Thanks,

I used a "medium" spring in my 84mm scissors and it fits just fine.

It definitely is the 74mm size but it works perfectly.

With a bit of fitting and banding you can use a 91mm spring too.



Ignoring the old single leaf springs there are actually four sizes.  Small for 58mm, large for modern 91mm; but there are also specific springs for 74mm and a different size again for 84mm and old 91mm.  Most stores will only carry small and large as that is all they are ever likely to be asked for.

Thanks guys,
I remembered I had an Executive in a box my Swiss Army pen came in so I stole the spring and stuck in the Salesman. I wish it was flat on the end since the scissors don't have a groove for the spring to ride in but it should work OK. I replaced a spring in a 91mm a few weeks age in about 30 seconds. I was beginning to think I would destroy the spring on this before I succeeded. I wish I had ordered more than one new spring. I was a real pain!
