    Edge Retention- best carbon makers

    Edge Retention- best carbon makers

    One drawback with San Mai is the carbon diffusion unless you use a thin nickel layer between the core an soft outer layer, but this is seldom used in Japan, more from good western blacksmiths ;) So with straight San Mai you will loose some carbon in the core, the more the longer the blade was...

    Edge Retention- best carbon makers

    This is not the case on my knives and there is no practical reason to temper Honyakis to higher HRC. Maybe with some makers marketing stuff to make mono with higher tempering softer so the high Honyaki pricetag seems to have some more reason ;) Regards Uwe

    Edge Retention- best carbon makers

    What i meant was that the Hamon and differential hardenig is for show, of course a well made Honyaki can be a good Pro tool also. But there is no practical benefit for kitchenknives because if i make knives i get the same quality on the edge with full hardening, Hardenening with clay and...

    Yes, a soft spine will not make the egde harder :D It is on kitchenknives only for show an works only on low alloy steels with not the best edgeretention possible. Regards Uwe

    Edge Retention- best carbon makers

    You must look at steel and HT combined, best steel with crapy ht is just crap ;) Best edgeretention for kitchenknives i got so far from Vanadis 23 and K390. S290 also hold an extrem sharpness very long, but for my taste not tough enough. Regards Uwe

    Spalted birch and cedar for knife handels

    I am using Imp-Resin 90, for me no need to try other resins, works very well and did not become soft from the heat of fast grinding. First blocks of birch ready: Regards Uwe

    S-Grind on a Budget?

    convex thinning on rotary platen Fast hollow grinding for the s-shape using a jig with 60 grit belt Foodrelase would be better with the hollow grind closer to the edge, but this way the knife has more lifespan for resharpenenig and maybe chip removal before touching the hollow part ;)...

    S-Grind on a Budget?

    Burgvogel factoryoutlet for 35€ so 60€ left for a fast thinning and kind of s-grind. Finish is not top notch but they work well in a pro kitchen So my sugestion is to find cheap knifes with good steel and a knifemaker near by to regrind them. Works with used Globals also. Regards Uwe
