What is the Rockwell hardness rating? Can I use this on my Yoshihiro Gyuto? (60 rockwell hardness rating)

You need to call the manufacturer for this kind of data. This is a consumer forum.

I have no idea what Rockwell hardness is or why I was asked to rate it. Sorry

yes , i use them on tool steels up to 65rockw. stainless is much softer but tough.

Actually Buck's standard knife steel is 420HC, not 440HC. This is used in their SELECT series. Most, but not always, of their mid-grade AVID series knives use 12C27 and their top of the line knives use S30V, which is a powdered metal steel. Basically each step up is a better grade of steel as far as maintaining an edge. Along with this comes the negative fact that each step up is a little more difficult to get the blade back to "shaving" sharp if you dull it really bad. To get more opinions on the subject visit Blade Forum. Lots of good info and opinios there.

It is 65Mn. With a Rockwell of around 58-60 I think (but I am not sure on the latter. Anyway the blade is darn good for the price. I have used the heck out of mine for heavy woodcraft when camping and hunting and it stands up very well. Maybe not the best blade on the market--but it may be the best (or at least in the top 3) at this price point. It will do the job as well or better than some blades that are far more expensive.

High carbon steel with a Rockwell hardness of 57/59, hope it helps. Chef Ryan

Sure! There's nothing magical about Global knives except they ship with a really nice factory edge. A lot of high-end cutlery makers make noise about sharpening their knives using a particular stone or device. I remember years back I bought a utility knife from Porsche Design and they said never to use a steel made out of steel, which led me to buy my first, scrawny ceramic steel. This is nonsense, of course. Except for ceramic knives, almost any knife can be sharpened on any steel - just do it skillfully. But let me reassure you, this sharpener works fantastically on my Globals, my Macs, my Wusthofs, my Porsche, even my antique carbon steel slicer from my grandmother. Go for it. Sure!

Since I could not find the kerf for the RW9231 blade on Rockwells web site, or on the blades package, I used my digital caliper. My caliper could only span (2) two teeth and (3) three teeth are needed for an accurate measurement, my reading showed .058"~.061" depending on how I held the caliper.Hope this helps.

The Rockwell rating on 1070 tool steel typically ranges from 52-58 depending upon the heat treatment. 1070 is a tough steel known for durability and resistance to chipping or breaking during cutting and light prying tasks. The 10 series is often popular for sword steels due to the qualities already mentioned along with relative flexibility. This particular knife is from thick bar stock, so flex is not the benefit, but for a tough, durable, inexpensive one-piece knife you couldn't ask for anything better. In direct testing against the retired Chris Reeve line of one-piece A2 tool steel knives, 1070 actually held up better in destruction testing according to one article I read.

Seki City Japan. Using VG-10 steel, FRN handle scales. It's a good quality knife and I did a lot of research before buying it, but at the end I bought it mostly because I loved how it looked. If it were me, I would buy an Ontario Rat Model 2. It looks more simple, but the craftsmanship is way better, zero blade play and built like a rock. And it is half the price. Also look at the Benchmade Mini Griptilian.

Get a good quality set of stones of different grit. I have not sharpened mine yet but have an assortment of different blades. I use either a 4 stone Arkansas kit and depending on knife and material, you can get one of these Woodstock SteeleX D1130 1000 Grit and 6000 Grit Japanese Waterstone

Granite has a hardness of 6-7 and the carbide steel point has a hardness of of 8.5 so thepoint should win out. It depends on how detailed a design you are trying to do since thetip will round some in use. There is the heavy duty #9929 point as an alternative.

I honestly dont know what the hardness of the blade is, due to the fact that the blades are not of a high quality these details are often not given with the product. However if you want a rough estimate on how hard the blade material is from my experience with them they loose their edge quickly while cutting boxes and its not very easy to get a sharp edge on them like on my ANSA knife. I would say that its the same as the hardness on regular 440 stainless steel nothing special here.

Jose, I just buy one of this, las year, and are very good, better than I was think it was. In my shun knifes, I olny use the ceramic roll (finhish polish), and stay very, but bery sharp all the time. I dont comend use the other disc, only if you have an very damage blade. By the way, this is for japanese angle knives, so, Not recomend to euro knives. But, I change the edge of an damage euro, to japanese, and now its very good to work.

Yes. It really depends how often you sharpen your knives. Please always apply light force in sharpening the knives. Good quality knives with good rockwell (hardness) will last longer.

Using a Taylor 210, with the recommended 13's. I went back and forth with the 80/20s and Phosphor Bronze. I prefer the 80/20s Bronze. I think they are just a little clearer. The Phosphor Bronze sounds balanced and real good, but a little deeper. But it all boils down to what suits you.
