Sandrin Tungsten Carbide Knives

Flexible tungsten carbide? How's that work?

My guess is they must be actually sintering it (usually this is done on Cobalt? see wiki below)...but I'm guessing they must be doing something different. Wish they gave clear info about it.
https://en.wikipedia.org/wiki/Tungsten_carbide#Cutting_tools_for_machining

Sintered tungsten carbide - cobalt cutting tools are very abrasion resistant and can also withstand higher temperatures than standard high-speed steel (HSS) tools. Carbide cutting surfaces are often used for machining through materials such as carbon steel or stainless steel, and in applications where steel tools would wear quickly, such as high-quantity and high-precision production. Because carbide tools maintain a sharp cutting edge better than steel tools, they generally produce a better finish on parts, and their temperature resistance allows faster machining. The material is usually called cemented carbide, solid carbide, hardmetal or tungsten-carbide cobalt. It is a metal matrix composite, where tungsten carbide particles are the aggregate, and metallic cobalt serves as the matrix.
 
It shouldn’t be a problem to sharpen Tungsten Carbide. Silicon Carbide abrasives were developed to sharpen WC. W is the symbol for the old name for Tungsten (Wolfram). On the Periodic Table, W is the symbol for Tungsten. SiC abrasives tend to be on the coarse side of the grit spectrum, so you might need fine CBN or Diamond abrasives to refine the WC edge.
 
Be interested to feel how heavy that is. Tungsten carbide is quite dense. (95% more dense than steel)

Yeah, no. Silicon carbide WILL cut tungsten carbide, but just. You'd be there for a VERY long time trying to do any serious work other than a quick touch-up. And you'd get a sub-par edge. N Natlek knows how to do it the right way.
 
sandrin torino knife review (first impressions)

review after some 10days use:
about rough nonpolished blade surface which some pepole find ugly>>> I do find it very very useful. It serves me as a very fine and hard file, using it as a nail file and also as a touch up sharpener for other steel and titanium knifes i previously own.
other obvious things: handle is perfectly coloured in order not to loose it, and handle material also have very good grip in a hand. Blade itself is razor-sharp. Non sharpened side serations (those although could be a bit rougher) are also useful as a fine file when knife is closed. I am eager to see next sandrin foldable-lockable knife in this blade material and in this price range (I do not find safe enough their slipjoint knifes)
As for a pocket clip:
I really would like to see it on the other side of a knife like spyderco knifes, titanium is perfect material for this since I can colourfully anodize it to give it a personal touch.
