The Janome 1200D Upper Knife will succumb to time and wear. One day it just won’t cut as well as it once did. But don’t fret, here is the replacement. Janome 1200D Upper Knife Fitting Take care when fitting the Upper Knife. We service and repair dozens of Janome Overlockers and other makes every year. So worn and damaged overlocker blades or knives are a common occurrence. In these cases, it is our general policy to replace both. The top knife moves up and down. Therefore, it is usually the one to suffer the most damage. Replacing only one knife risks a shortened life if the remaining knife causes damage to the new knife. This can often occur if the remaining knife has burred edges, which damaged or worn knives often do.
