Praticissima guida per coltelli per affilatura su pietra, permette di mantenere la corretta inclinazione della lama

Franchement ce n'est qu'un gadget peu pratique . L'inclinaison de la lame sur la pierre se trouve seule avec un peu de pratique .Autrement l'objet est correct mais voilà pour moins de dix balles c'est bien tout ce que ça vaut et encore bien cher

En la descripción del producto debería de poner la longitud del mismo. Sólo es válido para cuchillos de tamaño pequeño. Como adicional y propuesta de mejora deberían de decir el ángulo que tiene.¡Ojo! Que aunque diga Naniwa el producto es Made in China.

Very helpful as a guide for a beginner like myself. As expected it did put some scratches on my blade which is very wide at the spot where this needs to be placed. It was worth it to bring my knife back to a nice cutting edge.

I have been using knives "professionally" and I use that term very loosely, for over 30 years now. In my book, you either have the knack for sharpening knives, or you "cope" and develop strong wrists. I "coped" for 30 + years ! Sharpening knives on a whetstone, you need the correct angle and the right method. This Naniwa guide gives you a consistent 15 degree angle (I always used to use a shallower angle, that gives you a less durable and shorter lived edge) I honestly, highly recommend this Naniwa guide. I wish I had discovered it 30 years ago, it would have saved me a lot of heartache, I can tell you. This guide will give you the consistent angle you need, for everything else I recommend that you check out Youtube.

I tried a lot of guides back when I first got started with water stones and this one became my favorite. I just got some more after giving some away and it's the same high quality. I have a few of Naniwa's Chosera stones and they're some of the best you can get. Right now I'm using some 水山 (Mizuyama) stones that are a little softer for high-Rockwell blue & white steel knives and this guide does a fine job of holding the blade in the right position while putting minimal wear on the stones. The ceramic rods are very fine and almost brought to a polish so they glide on the stone effortlessly. Whether you're just starting out in freehand sharpening or you are a seasoned student, it's a good idea to have one of these around and this one is the best you can get.Sharpening straight-edged knives like santoku and usuba/nikiri is very easy. With curved blades, adjust the guide angle to keep it parallel to the edge, as shown in the pic. Tips can be tricky because the guide will tend to bottom out and the blade will float above the stone. Pull the guide back, off the spine, and you will be able to get the tip onto the stone and sharpen it. This is one aspect that makes it a real incentive to learn how to sharpen freehand without a guide. It goes so much quicker than having to keep repositioning a guide and it's so much easier to achieve critical sharpening at the tip. Plus, the OCD in me likes the idea of one continuous sharpening motion across the entire edge than constant stopping and starting. But of course this is a skill that takes a good deal of patience and personal investment and it's nice to have one of these around to build your confidence.
