Sandrin TCK Tungsten Carbide Knife - Does Anyone Have One?

I believe that TC has been around a long time . There are probably good reasons (eg brittleness) it's not used in knives much . Unless they've got a way to make it tough now ? :confused:

Point is this ..........CARBIDE content :) stellite or talonite are about only 50 HRC .....Can REX 121 with 71 HRC outperform them in wear resistance ?

I understand what carbide content means and don't recall asking for anyone to clarify what it means.

Sorry for that , I thought that you don t understand what @eKretz is trying to explain in his post and you ask him this ..... And your point is what?

A hardness test won't always tell the whole story. Most hardness tests are checking for indentation, which is useful in general terms but doesn't really reflect hard carbide particles' true hardness. Think of it this way - put a bunch of diamonds into some modeling clay. You can EASILY push the clay, but the hardness of the diamond wouldn't be reflected well in an indentation test.

From the thread, it appears that, aside from that Cedric&Ada guy, no. No one here seems to have one.

I admit I’m curious, but I’ll wait for some more reviews of how it does on daily type stuff, and cardboard. And sharpening.
 
My experience sharpening steel with diamond has certainly not been that it is as easy as filing wood with a metal file.
 
Well , for what it's worth....... 0.9mm behind edge and 42° cutting hollow grind edge....my meat chopper have better edge geometry :) Would I buy this ? No ! No matter how flexible it is ....it is Tungsten carbide .It will chip easy and risk to break at half is high........it s not good even for apple :D

The spine is .9mm not the thickness behind the edge :confused: The 42 degree inclusive angle is likely to help protect against chipping.
 
I can't find any kind of proof of "flexibility " or toughness . I'm very skeptical of these claims . If they really had such a revolutionary process , it would have found wider applications by now beyond a few niche knives .

This technology has excited me more in terms of a WC knife.

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 ..................

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