Hi Cindy:
  First it is not necessary to take appart a knife holder daily. For what you describe
  this techs acts as some do, thinking that they are like "independent contractors"
  within the lab setting able to do anything the want regardless of general rules.
  Do you have an SOP that addresses this cleaning procedure? If you don't you
  can write this aspect and have everybody to adhere to it.
  With some statistics about recuts required for bad technique you can also try
  to convince her. 
  You could also get advise from the sales representative regarding this practice.
  If everything fails you will have to impose authority on the issue.
  Hope you will be able to reign in this stubborn tech.

  This is a question for those techs who cut on a manual Reichert-Jung 2030.
I have one tech who insists on completely taking apart her knife holder everyday to clean it. She removes the springs and all. This person is also the only tech who has trouble cutting and is constantly having to recut a specimen or nearly cutting through needle biopsies.
I maintain that handling the knife holder spring so much causes the problems (knife won't clamp tight evenly, chatter and skipping). The other techs, including myself only dismantle and clean the knife holder about once a month. We have had to purchase new spring and bolts for this microtome about every 6 months, whereas the other microtomes have never had to be replaced. How do I go about telling this person to quit cleaning so much.
I have had the knife holder and microtome serviced to make sure there is nothing else wrong. I have cut on that machine and find it cuts beautifully as long as you don't take it apart after every 10 blocks to clean behind the blade.

Any suggestions would be greatly appreciated,
