I have an inexpensive Japanese mandolin that I use a lot. It is incredibly sharp...I've successfully removed the fingerprints on two of my fingers using it
Scalloped potatoes, sliced cukes and carrots for picking, add the "teeth" and shred daikon, papaya, mango etc, for "Som tum" salads.... Just watch your fingers...
Its a "Benriner" brand.... a whopping $25
