Thanks for the detailed answers Connor. :)

This is a really interesting knife, in that they haven’t just relied on the marketing potential of ‘tungsten carbide knife blade’, but really seem to have done their homework in terms of using thin bladestock, thin bte grind, acute edge angle relative to carbide volume, innovative lock, fine carbide size etc.

I’m assuming it’s a completely ambidextrous in setup as well - looks like the clip can be changed to lefty carry?

The sharpening service is cool too, although it probably wouldn’t work for me if I was using the knife frequently, having to send it overseas and all.

Larrin said that some people were reporting difficulty in getting it back to similar sharpness to the factory edge, which is interesting, as you would expect skilled sharpeners to be able to exceed that level. Sounds like an interesting challenge.

What do you think they mean exactly by diamond lapping stones?

I’m wondering if the older ‘legacy’ Venev stones might be a better bet than the OCB stones, as they also have an approx. 7μm abrasive in the binder, in addition to the advertised diamond grit size?

I have one of the legacy 1200/2000 bonded resin Venev benchstones which I would consider using.

Another option might be to use diamond powder on a glass plate. I bought some 50,000 and 100,000 grit vials of powder from a gemstone lapidary supply house a while back. You could potentially make a high concentration slurry with that. The lapidary recommended making an emulsion by mixing the powder with a little kerosene in something like a shot glass and then thickening to your preferred consistency with petroleum jelly/Vaseline.

I’m considering getting one of these to play with, so I’m interested to hear how you go with sharpening the knife, once the time comes. :) :cool:
No problem Cambertree! Yes it is 100% ambidextrous. The clip is reversible.

Sandrin has a video on YouTube showing how to sharpen their TC knives. (https://youtu.be/KRk9_88LfXs) They recommend starting with a 30 micron diamond lapping film, then 9 micron, then 3 micron. I imagine you could go even finer for a higher degree of sharpness. Oh and they recommend using oil on the blade as you sharpen.

I have the same 1200/2000 Venev stone but I never used it much at all because it seems to load and glaze so quickly. If I don't get any lapping film then I'll probably use the Venev diamond stones.
The diamond powder would probably work fine if you were good enough at freehand sharpening, but I might try the easy way first. ;)

Just placed an order with Jende Industries for everything I need to sharpen this crazy tungsten carbide blade. 4 different grit sizes of lapping films plus a bunch of 1x6 acrylic stone blanks for my Hapstone. I feel pretty well prepared at this point. ;)

Cut 8 feet more single ply cardboard and about 70 feet of regular double ply. Slices receipt paper fine, and still shaves.

Cut some more double ply cardboard. Did more push cutting this time, rather than angled slicing.
The edge doesn't shave, can't really slice hanging phonebook paper, although copy paper slices fine. It feels pretty toothy now, probably from the nature of the edge wear.

I also cut myself again last night, same way, same finger. :rolleyes:

Today, I cut about 50 more feet's worth of double ply cardboard boxes. We've been getting in a lot more packages and such than normal.

I also went to town on a piece of pine wood, carving hard and forcefully, no differently than I would treat any steel blade. It was a tough, resinous piece of wood complete with knots. I powered right through knots and all, carving it down to almost nothing.

After this I couldn't see any kind of damage at all, in the edge. That's pretty good IMO for 71 RC tungsten carbide!

The edge cannot shave hair in any real sense (still get a few if I scrape hard enough) but it still slices copy paper well. And I find it'll even still slice phonebook paper (somewhat reliably), if I cut "across the grain", i.e., the short way.

I'm going to use this knife mercilessly until my sharpening equipment arrives. Hopefully I'll have a nice dull knife by the time it comes.

I will say that, what with the thin edge, decent angles, and super thin blade stock, the Sandrin Torino is easily the best slicing knife I have ever used. During cutting, it feels more akin to a utility knife blade, than most EDC pocket knives. :thumbsup:

~18.5 degrees per side. Very middle-of-the-road.

More testing!

Here's the level of sharpness I started at:
Image

I had some 3/8" yellow polypropylene rope - very tough stuff - the individual fibers are like fishing line. Made 200 cuts on a cutting board. Result:

Image

Then I cut some cardboard (double ply). In total, I cut 175 feet.

Image

It's more coarse at slicing the paper. I can see that the edge has lost the smooth look from factory and is a lot more rough.

Last, I push cut through a bunch of stranded copper wires. I made 11 cuts total.

Image
Image

The copper wires did not damage the edge at all.
It still slices copy paper, but no denying it's getting pretty rough.

Thanks! It's been fun and interesting so far. I can't wait for the sharpening gear to arrive. Then the fun will really begin. ;)

I'm very impressed by the strength of the edge so far. If I'm going strictly by experience I don't think I could say it's any worse than Maxamet. For such high hardness and high carbide volume, that is quite an accomplishment. Sandrin obviously did their homework on this stuff.

In the couple days since that last "test", I've cut up a number of cardboard boxes and done a bit of food prep along with other general EDC use.

Today I was cutting some thick plastic pallet banding. This stuff is mean and has caused other edges to roll or chip. The tungsten carbide took it without any visible damage.

Then I attacked a 4x8 foot piece of super stiff, solid cardboard. It's almost like wood and takes a ton of pressure to push the blade through.

Image

Maybe 60 or so feet's worth of cutting.
I was cutting with my thumb on the spine, and it was only afterward I noticed the thin spine had split my thumb from the pressure exerted. :eek:
Image

At this point, the edge is really rough slicing paper and a little unreliable. It is still plenty sharp enough for EDC, but at this point, I may give it a break until the sharpening stuff comes.

Ouch. Looks like you'll need to break the edges on the spine before attempting those cuts again.
