Wes, we did WD-40 the spring. Tim thought it was just worn out.
After trying the rotating handle on the Fiskers, I wasn't that impressed.
I have not heard of the Leyat. If the spring does not fix my old pruners, I will see if I can find a local seller. Like you, I like to try them in my hand before buying.
I don't think anyone sells the Felcos locally anymore. Nursery that I bought mine at is no longer in business.
Thanks for the great info!
