  • Another Kitchen Appliance

    If you are a weekend chef, or only make basic meals - you might find this to be old news after a while. It is possible this device will collect dust along with your other kitchen gadgets that have lost their novelty. To avoid this, think of all the cutting you do on a regular basis. Also, consider how often your knives feel dull. If you find that your knife collection is rarely ever used anyway, you might be disappointed with how little you end up using this product.

  • Sanitation Issues

    While sharpening clean knives all at once will not be a problem - sharpening them individually while cooking might prove to spread germs more easily. Furthermore, since this product also sharpens tools - you might find your Sharpdini in the garage as someone else in your household tries to sharpen their tools. Thus, such multiple purposes might not be sanitary considering how much less clean a garage can be compared to the standards of a kitchen. Multi purpose might seem like a good idea at first until you have to continuously sanitize this product as it is taken from a work station back to the kitchen.


  • Knife Stones

    Chefs have been using knife stones for years and have been able to perfect the grit of each knife stone.

Of course, beginner knife sharpeners need to use a grit that is less abrasive so that they do not shave off too much of their knives accidentally.

Tips & Tricks
