Mandoline Slicer | $9 | Amazon | After $2 off coupon

Unless you have perfect knife skills and a ton of time on your hands, mandolines put precise, uniform cuts in the realm of possibility. This mandoline slicer is just $9 today, the lowest ever.

It’s not the fanciest model, but would be good for people who are beginners and not looking to drop $80 on a professional-quality mandonline. This one comes with five different interchangeable blades: two for shredding, two for slicing, and one for making wavy cuts, like for waffle fries.
