Sandrin TCK Tungsten Carbide Knife - Does Anyone Have One?

I wonder how they measured that it is 42 degree inclusive angle when it is hollow grind edge :D Do you know ?

It’s an amusing observation. However, there are still various ways of expressing/measuring the angle.

I think this is just conventional TC in a kind of San Mai composite sandwich . Cool but nothing revolutionary .

The spine of the blade fibre reinforced aluminum providing a very flexible tough back edge with that WC edge.

I haven’t seen how Sandrin is supposed to combat the brittleness problem of WC in their knives yet.

Liars...................:) They MAKE controlled and repeatable CUT ! Like hammer on spine to cut nail , proof nothing .Try to cut that same nail only with knife , and see what will happen ..................

That’s what they were doing. Cutting stainless steel rod 6 times with the same WC knife using the same spot on the knife.

Until proven otherwise , I've got to assume the new and improved "flexible" TC is total marketing BS or at least highly exaggerated . Why just put this on a few high end knives ? Think of the huge market potential for industrial and consumer tool applications . Does NOT compute !

Industry use this kind of blade for long time ago , full tungsten carbide blade or only edge with TC ....but that kind of blade make cut in controlled and repeatable manner ...
Look here foe example .... http://www.zuffinetti.it/en/prod/cross-cutting-knives/

That video clip is published on Jun 16, 2015 , why that knife is not for sale yet :) Or it was so revolutionary that they sold it the same day .....just like @Nathan the Machinist sell ten knives in one second here ;)

They are an armor company. It was just a side project for them. Also I chose that video because it was the one I remembered. I haven’t really followed up on the knife.
 
I obviously don't know what is in this particular alloy but I have personally seen 0.5" W-alloys shatter like glass when dropped.

Well , that make sense :thumbsup: Look , I don t want to look like I have something against you or against this TC knife , if someone like it is free to buy it . TC is very brittle to make knife from that , even only if it is on edge .... I have it and I've tried it . We have plenty of hard steel that are barely acceptable for knife , and they are many time better then Tungsten carbide in almost all characteristics except hardness ...........

I recently bought a Sandrin dellatorre and, while I'm no metallurgist and don't plan to drop the blade onto concrete anytime soon or pry wood from a log, I can confirm that the 3.1" long 0.9mm thick blade is flexible, fwiw...20210110_201029.jpg
 
I've got a Torino and have been very impressed. Build quality seems excellent and the edge is still flawless after some fairly heavy use. Zip ties, 14 gauge wire, cardboard, etc. No noticeable change.

The handle design is questionable, but it's a great knife.
