Never slice frozen or stale bagels as they will dull the blade. Slice your bagels before you freeze them or thaw frozen bagels before slicing.
Steamy, moist or 'sticky' bagels may compress or squash during slicing; allow bagels to cool off before slicing.
Flavored bagels may leave a sticky residue on the blade. Regular cleaning allows for the Bagel Guillotine to work at its maximum efficiency.
