Zwilling/J.A. Henckels, a noted German (I believe) cutlery firm, says in a brochure it is using something called Sintermetal Component Technology for most of its knives over 6" blade length (they use traditional drop forge for knives below 6"). Apparently they can alter the composition for blade, bolster tang as desired. Is this the same as particle forge metallurgy? I'd like to learn more about this technology. Is this anything like the casting technology pioneered by Bill Ruger to produce components that are extremely strong and close to finished product?
 
Alberta,

Here is a page on Crucible particle metalurgy. http://www.crucibleservice.com

It is different than sintered metal. Hopefuly the experts will be here shortly to help you out

sintered refers to powdered metal process in a mold at great pressure and usually high temperature. kinda like taking a handful of sand and squeezing it as hard as you can. I believe RUGER pours molten metal into a mold to solidify. This makes a one piece casting.
 
Many of the gun companies use Metal injection molding. Its like plastic injection molding except they use metal in a high pressure injection mold. This produces a fantastic part that the tolerance's are very simular from part to part.. Makes nice checkers 3 d parts like saftey swich's ect also.

Sintered maetal can be several types of process. The metals I have seen are bronze and steel . For the steel they used 300 ton and carbide dies to sinter metals particals.
They could hold .003 with this method.

The store I work in part time carries both the Henckels and Wusthoff lines of Kitchen Cutlery.

I have to say that I prefer the balance of the Wusthoff Forged Knives over the Henckels Sintered Metal Knives. The Sintered Metal Process may provide some benefits but balance is not one of them.

I also want to be careful to distinguish the Sintered Metal process from Crucible Particle Metallurgy. I love the CPM440V blade on my BF Native.
