Protect your investment

Since all knives dull with use, it's important to protect your cutlery investment with proper care. The long-term performance of a knife depends on how it is sharpened.

Blades made from the best steels last longer, but even the best knives will dull over time - and your original factory blade will last for the first few days or weeks of active use.

For over 99% of a knife's life, the performance of the edge depends on how you sharpen it. Replicating the original factory sharpening isn't particularly practical, especially since today's modern knife sharpeners can give any knife a better factory sharpening.

The Chef's Choice 463 Pronto Asian / Santoku Handmade Knife Sharpener is the fastest manual knife sharpener on the market. The Model 463 has two stages, one for lapping and one for lapping/polishing to achieve a strong, durable curved edge. Level 1 and Level 2 use 100% diamond abrasive, and a diamond wheel will retain its shape indefinitely (unlike ceramic wheels which lose their shape over time). Cross-grinding technology creates extremely sharp edges with plenty of bite. The diamond blade grinds the inside and outside of the edge simultaneously to obtain an excellent burr-free edge. The 2 micron diamond abrasives give the knives an extremely sharp, polished edge. Precise bevel control increases up to 15 degrees for ultra-sharp Asian-style edges. The pronto is safe to use with straight and serrated Santoku knives, as well as other double-bevel Asian knives.
