Members CalgaryJim Posted February 11, 2024 Members Report Posted February 11, 2024 I just bought this knife, $95 CAD, about $70 US. The handle is nice, the blade is 9rc13 stainless steel. It was sharp out of the box but I sharpened it with a 1000, then 4000 wet stone, then honed it with green rouge. It doesn't seem to skive as easily as a Weaver 24mm blade I have. Unlike the Weaver, the edge looks the same as the rest of the blade, there's no shinier metal for a few millimetres back of the blade edge. I'm thinking I should have instead purchased a skiving knife from Japan. Is anyone else familiar with the Tandy blade and what has your experience with it been? Quote
Members Arturomex Posted February 11, 2024 Members Report Posted February 11, 2024 (edited) A friend of mine bought that Tandy knife and he wasn't very happy with it. I tried it a couple of times and it didn't blow my skirt up either. It was fine for just cutting but it didn't seem to skive well at all. I don't know why. I buy my knives here: https://leathercrafttools.com/tools/manufacture/knife/list/ I particularly like the Hidetsugu knives. You're getting a softer steel on top with, I think, Hitachi blue or something similar as the cutting edge. They come with unfinished handles and I put a couple of coats of water based Varathane on them. I sharpen starting with either 600 or 800 grit, work down to 2000 grit, strop with green compound and they're razor sharp. I'm pretty religious about stropping after every use and once these are in shape, they don't really need to see a stone again. These are very similar to the Weaver knife you show but the price is a lot better, even after shipping. (FedEx - about one week to Alberta.)

Members DieselTech Posted February 11, 2024 Members Report Posted February 11, 2024 I recently bought the TandyPro Damascus trim knife. Super nice knife, but was the tip was dull out of the box. Kind of made me irritated, but I was expecting it. Whatever composition their damacus is, it's super hard. It should make for a nice knife once sharpened. Quote
Members Simplejack1985 Posted February 12, 2024 Members Report Posted February 12, 2024 I picked up a skiving knife from an old man making them in a back alley way in Tokyo. One of those once in a lifetime random scenarios. With that said they skive nice. I still prefer a French edger or the custom skiving knife my buddy made me. Quote
Members TomE Posted February 12, 2024 Members Report Posted February 12, 2024 One of my favorite skiving knives is this cheap knockoff https://a.co/d/58YIeFR. I did reprofile the blade before we became friends. It holds an edge reasonably well, especially for what it cost. My other favorites are rounded blades including an Osborne #67 and a Dozier half round knife. So my philosophy is there are a lot of tools that will do the job and I just need to work on the blade until I'm happy with it. Quote

Members Mablung Posted February 12, 2024 Members Report Posted February 12, 2024 Those kinds of high-ish carbon stainless steels generally benefit from a higher-grit polish before stropping. I don’t know exactly why, but the ones I have used respond better to one more polishing increment before stropping. So, I’d polish it on an 8000-grit stone before taking it to the green compound, as you’ll reduce the scratch size imparted by the 4000 and then be able to smooth them out better on the strop. Also check the bevel angle to make sure it’s consistent. A loupe is very helpful for an edge like this that needs to be uniform. Quote
ljk Posted February 12, 2024 Report Posted February 12, 2024 Very good explanation from Mablung. The chemistry should allow for heat treating to a high hardness. The tempering process will dictate the final hardness. Producers play that game of hardness over 60rc vs.toughness 55-60rc. Go through the sharpening process as described by Mablung than use the green stuff for touch-up. The only way to check hardness is using RockwellC tester. I think some of the boutique steels are nothing but a hustle. What they sometimes do is use a bunch of letters and numbers to confuse the customer. Plain old cheap 1095 high carbon steel heat treated properly will make a great knife, albeit poor corrosion resistance. Quote

Plain old cheap 1095 high carbon steel heat treated properly will make a great knife, albeit poor corrosion resistance. Appreciate the vote of confidence, and the point about the heat treatment is an important one that I omitted. If the heat treatment is like that of my Stohlman-branded round knife from Tandy, it's a bit finicky. That knife requires a great deal of polishing to get a really good edge. I'm not sure whether it's 9Cr13MoV like the skiving knife you're looking at, @CalgaryJim, but the characteristics are very similar to a 8Cr13MoV folder I have (only slight differences in chemistry, but enough to make the 9 a bit tougher). Something else I thought to add to my explanation, above, is to make sure you check the back side of the blade for a burr. Be very consistent with the main bevel, but also be sure to remove the burr from the back of the blade. Because the bevel is a chisel-grind, i.e., a single bevel, you won't take the burr off when you sharpen the other side of the bevel, because there isn't a second bevel. Leaving that burr will cause issues swiftly. As long as you're careful with the sharpening process, it ought to sharpen up decently. Whether it retains the edge is a different matter, but smooth skiving seems to require a mirror-like polish on a carefully tapered edge. Edited February 12, 2024 by Mablung Quote

Regards, Arturo Thanks Arturo, I just placed an order for a Hidetsugu knive from that website. I skipped courier service and went with unregistered mail for the price since the knife was only 3,870 yen.
