i have used my sebbie to cut plastic bumpers off cars at crash scenes. that was tough on the edge, but i restored it with a flat ceramic stone and a leather strop. i have cut a shoe lace from a guys throat that tried to hand himself. pretty tricky with a razor sharp sebbie. last night i found out that its a decent bagel slicer. i'm going to retire the old girl. i'm about a month into a three month wait for a large new model sebbie with a polished blade and no clip or clip hole, they will pull the handle from production before that step. like the song says the waiting is the hardest part.
