A perfect companion to a chef's knife or santoku. A petty knife is what the Japanese call our "utility" or "paring" knives. If you already own a small utility knife or just don't find that you use them much, and if you want something that can be more versatile and used like a small slicer or "sandwich knife", then this is the perfect length (it's long enough to be used like a small chef's knife really). These rectangular dimples also look REALLY cool and match the rest of the set and don't add much to the cost, so it's nice to treat yourself to this little luxury if you like the look. As with all the Sakai Takayuki knives, I find this a great value, very well made, and with a super sharp, accurate and carefully finished edge. Made of a hard and long lasting special alloy stainless steel from Uddeholm Sweden. This is a super-sharp knife that will be sure to offer years of pleasure in the kitchen. Note: dimples are only on the one (front) side.
I'd recommend the Idahone fine ceramic hone for regular/daily maintenance of the edge. As with any knife, use the hone regularly and you'll keep the edge in good shape for a long time before you need to think about doing any serious re-sharpening or real grinding and refinishing of the edge.
NOTE: This knife is sharpened almost entirely on the right side, which means it's not really suitable for left-handed use.
