Sakai Takayuki SPG2 Kengata Gyuto 190mm

Not quite - and it is the single most common point of confusion when people shop for a kiritsuke. The two knives share the same striking angled, reverse-tanto tip, but underneath that tip they are very different tools.

A K-tip gyuto is normally a double-bevel knife: it is ground on both sides like any Western-style chef's knife, so it is forgiving to use, and sharpened exactly the way you would sharpen a normal gyuto. You get the dramatic kiritsuke look with the everyday usability of an all-purpose chef's knife.

A traditional kiritsuke, including the kiritsuke-yanagiba (slicer), is a single-bevel knife, ground on one side only. It is historically a master chef's knife: it takes real practice to use well, is set up for right-handed users by default, and needs single-bevel sharpening technique to maintain.

So if you want the kiritsuke silhouette with no learning curve, choose a K-tip gyuto. If you specifically want the traditional single-bevel discipline - and the precision it allows on fish and vegetables - choose a true kiritsuke. At Knives and Stones we stock both, and each product page tells you which construction you are looking at.

SG2 is my go-to recommendation for anyone who wants a stainless knife that performs like carbon steel without the fuss. At 62 HRC or more (Takefu's figure), it takes a screaming edge and holds it far longer than VG-10 or AEB-L, all while being rust-resistant. You get the best of both worlds: no patina worry, but real cutting performance.

Neither is objectively better, it just depends on whether you value stainless convenience or a laser-sharp carbon edge. Go with SG2 if you want a knife that holds a screaming edge without any babysitting. Choose AS if you are chasing the thinnest possible edge and don't mind wiping the blade down after every use.

SG2 is a powdered stainless steel from Takefu, rated at 62 HRC or more. It is tough and resists corrosion, which is why I reach for it when working with acidic foods. Aogami Super is high carbon, and Proterial gives it a hardening hardness of over 60 HRC. It sharpens to a hair-whittling edge that lasts slightly longer than SG2, but it will rust if you neglect it.

Yes, R2 and SG2 are the same steel — R2 is the name used by Kobelco Steel, and SG2 (Super Gold 2) is the name used by Takefu Special Steel for the identical powdered metallurgy formula. SG2 / R2 is a powder (PM) steel from Takefu Special Steel, Japan, with a composition of 1.25% carbon, 14.0% chromium, 1.8% vanadium, 2.3% molybdenum, and a hardness range of 62–64 HRC. So if you see a knife labeled R2 or SG2, you are getting the exact same material.

Sakai Takayuki (堺孝行) is a brand of Aoki Hamono Seisakusho (青木刃物製作所) in Sakai, Osaka, and the company's own page says so directly. The trademarks for 堺孝行 and 堺菊孝 were registered in 1964.

The company started in Tondabayashi, Osaka, in 1947 as a wholesaler of Sakai forged knives, moved its office to Sakai in 1963, and built its Sanpo factory in Sakai in 1977. So when you see the Sakai Takayuki name, that is Aoki Hamono's own line.

Sakai Takayuki knives are made by Aoki Hamono Seisakusho and its craftsmen in Sakai, Osaka. The company's own traditional-craftsman page profiles its named Sakai smiths.

Sakai works by division of labour: forging, grinding and sharpening are each done by a different specialist. Aoki Hamono's Sanpo factory, home to its smiths and sharpeners since 1978, added an automatic grinding machine for Japanese knives in 2015.

A honyaki is water quenched with sword-style hardening, so it usually runs about 1 to 2 HRC harder than a comparable knife that is not honyaki, though that varies by maker. The quench has a high failure rate, and that craft is a large part of the price.

A honyaki also needs more care. If your kitchen is busy, an everyday line such as the 33-layer or 45-layer VG10 Damascus, which share a VG10 core and differ mostly in looks, is the easier choice; if you want a harder edge and the craft itself, a honyaki can suit you.
