[Histonet] microtome blade

Dear Histologists, After you have completed sectioning for the day do you remove the blade? Is it safer to keep the blade locked in place? Is it a safety issue? Or is it a policy set by your workplace? Thanks, Patricia M. Zerfas National Institutes of Health Bldg 28A Room 112 MSC 5230 9000 R
