Tanaka Petty SG2 Ironwood 90mm is Shigeki Tanaka's top-of-the-line kitchen knife. This is a very rare piece. Not only is the SG2 powder steel one of the best steels to make kitchen knives of, but the looks of this special Tanaka are simply special. Very pronounced, black-ish 33 layers of Damascus pattern on the blade, attached to a yo-style (Western) ironwood handle for durability, connected with a stainless bolster for a more comfortable grip.
The knife is stored in a traditional wooden box and offers a very special collector's experience thanks to its features and design. Suitable for Japanese knife connoisseurs who appreciate handmade and traditional Japanese blades.
Petty knives are meant for all those smaller tasks where larger knives are considered unwieldy, both on and off the cutting board. It's an indispensable knife in any kitchen and can be used for peeling, chopping, slicing and decorating food. Thanks to its wider profile, it can also be used for independent work and cutting on the chopping board.
SG2 steel is high-quality powder steel, easy to maintain and sharpen, and has long edge retention. This powder steel contains around: 1.25 - 1.45% carbon (C), 1.80 - 2.20% vanadium (V), 14.00 - 18.00% chromium (Cr), 2.30 - 3.30% molybdenum (Mo). In short, very hard steel which will keep a smooth, sharp edge for a long time.
The core layer consisting of the harder SG2 steel was sandwiched between 32 layers of softer steel. This technique is called san-mai damascus and is used to protect the hard (but delicate) core from outside factors and physical impacts, which could lead to breakage.
It has a double bevel (symmetrical) blade with a hamaguri grind.
The blade has a 33-layer black (etched) damascus finish (see article Blade Construction: Blade Finish for more). It also bears a kanji inscription that reads: 名匠誠貴作, which translates to 'Made By Master Craftsman Shigeki.'
The Western style (Yo) handle is made of a very dense and durable ironwood. The blade is secured to the handle with 2 stainless pins, both of them feature a mosaic design for the extra lavish look! A stainless bolster was added for comfortable grip and balance.
Ironwood, known as "tetsuboku" in Japanese, is a prized material widely used in traditional Japanese cutlery. Handles made from this wood are renowned for their exceptional hardness, durability, and striking textured patterns, which provide both functionality and aesthetic appeal. The ironwood gives the knife a natural warmth, improves grip and ensures durability of the handle.
