I bought this with skepticism thinking yeah right this thing won't cut hot butter but I figured it isn't expensive and I had just moved and needed some new kitchen untensils so I bought it. Got home and with anticipation to try it out I opened it up and grabbed a cucumber from the fridge. I was shocked the Yoshiblade peeler took seconds to peel it and the Yoshiblade knife sliced great and smooth didn't need any pressure or sawing motion. Since I have used it for every kitchen need. It really works great on slicing tomatoes you can slice paper thin slices if you want. Please use caution this blade is super sharp and will slice with ease. I recommend this to everyone, just be sure to follow the enclosed instructions and I think you will find this product very useful and a great addition to your kitchen/cooking needs.
