I understand, Julie. I knew I wouldn't have the hand strength to take them apart or get them tight enough when finished, which is why I asked my husband to do it for me. I'm so glad I did. I also have some Felco spray cleaner/ lubricant and he cleaned them well while apart. They truly are like new, and the new blade only cost $15 on Amazon.
(I seem to get an awful lot of boxes from Amazon...)
