People just need to learn how to use a knife.
Yes, it's strange how many of these thingamagoos are just simple cutting-implements, isn't it?
But then... if you don't have a decent knife, or know how to sharpen the one you have, some
of the drawer fillers actually do
a decent job. I'd love to have a decent mandolin -but they're pricey and a good knife does the job for me.
