Hi brudders,
I'm a fan of cold steel since the day I started collecting blades though my first piece was an Almar kitchen knife, =) COLD STEEL performs man..
Anyways, I have the entire collection of Cold Steel's Tanto series, the latest version as I got the entire set in 2007. They all come in VG-1 San Mai 3 stainless which means that the core of the blade is of High Carbon of say about 60 HRC. The laminated pieces (ie: The core blade is the Ham of the sandwitch, the bread are the laminated pieces) are made of softer steel ie lower percentage of carbon and higher percentage of chromium so as to resists corrosion and also to allow some flexibility to withstand impact and not chipping off. If the entire blade is like super hard, high carbon it will be brittle like a brick.
All of my tantos perform well, sharp edge that has good retension. The magnum tanto XII is kinda like a mini sword. However, to me I think the tanto point is like THE best point for stabbing. The tanto point has been invented long ago, its just that cold steel has improvised it so well and yes they have proven to be through. I really did use my master tanto in san mai 3 to stab through a car bonnet many times, no problem man. Tip and edge undamaged.
When I buy CS knives now, I only go for the San Mai 3 pieces cos their flagship steel the Carbon V 1095 steel that was so well reknowned are no longer in production. Carbon V is strong and super good value for $. However they rust easily at the edge if not oiled very constantly.
I personally have the San Mai 3 Gurkha Kukri and luckily managed to buy one Carbon V Satin polished Gurkha kukri. Both perform almost equally just as well, 9 inch tatami otome in one swing no problem. But the Carbon V piece has to be maintained ( oiled ) alot much more constanly.
Hence, think of the San Mai 3 as an 'advancement' or improvement, the Carbon V is sheer raw power.
If any bros out there wanna get a super high powered tanto or any japanese styled blades, I recommend
www.kanetsune.com This company has been forging blades for over 800 years. very famous for layering 15 layers of damascus steel on a super strong blue steel 'core' blade. Blue steel is is made by Hitachi Metal Company Ltd. It is one of the top grade steels used in many industrial factories for heavy cutting purposes eg: slicing through thousands of sheets of paper at a time or maybe even cutting through thin metal plates. They actually have up to 1.05 % carbon in their steel yet maintain the blade's flexibility by adding silicon, lastly adding chromium to resists corrosion. Blue steel's HRC is about 63. tat's hard.
I have got a kukri that is made of the abovementioned 15 layered damscus blue steel, custom made by this company. The normal piece comes only in 5.19 inch blade. I had them custom make me a 17 inch blade piece, overall length 23 inch.
Hope I have helped out here.
