Snoop's Take

The Orange Ninja 4-Stage Knife Sharpener by Sharp Pebble is a manual tool engineered to restore and refine kitchen knife edges with a four-slot system. It quickly transitions from coarse blade repair to fine polishing in just a few strokes. User feedback is as mixed as a well-shaken cocktail, with praise for its simple, lo-tech design—one reviewer even noted, "I love the simple idea and lo-tech of this little invention." However, sentiments are tempered by concerns over value and potential blade damage, as several users critique its price and abrasive quality. In conclusion, while the Orange Ninja offers innovative, user-friendly sharpening for everyday use, caution is advised due to its design limitations and inconsistent performance. Recommended for casual home cooks who value ease-of-use over precision, but professionals might look elsewhere for high-end results.

Allin all, no, it doesn't suck as much as a pull through, and no, it's not as good as a whetstone.

Positive Feedback

Sadly yes, price is silly, though I love the idea.
