For Cliff Stamp: sharpening VG10

Cliff Stamp said:
That would indeed seem to be a more productive direction as Spyderco has compared 154Cm and VG10 and found VG10 to be pretty much a superior blade steel, 154CM isn't a blade steel and VG10 was so designed. The same manufacturer who makes VG10 also makes P/M stainless which are also designed as blade steels.

That's why I said "Less Moly and more Cobalt" ;-)
Or, in other terms: there should be a valid reason for Kevin Wilkins to rely on using 3.2mm thickness for N690 (same chemistry as VG10) for his folders, and 4mm for other stainless steels :cool:
Yes, Tokko makes Super G1 and Super G2 but I din't find any literature about them, unless they're SGPS used by FK.
 
They are, it used to be G1 and now they are moving to G2. They have a number of nice nonstainless steels as well. It would be nice to see Spyderco do some runs in them.

So SGPS was G1 and FK 3G is VG2 (sides)+ G2 (edge)?
I noted that now P1 folder is also in 3G blade configuration and Cocobolo handle. Where could I find it?

Cheers
 
I emailed the manufacturer and the said that companies using SPGS were G1 but they were switching to G2. Fallkniven tends to be fairly open and honest about their products so you could always ask them directly.

Yes, they definitely are, and their supports rocks.
Just wondering if it is wise to switch to 3G steel (VG2+SGPS) because I'm a little worried about VG2 bending resistance.

VG-2 is very similar to the Sandvik stainless, it would be very well suited for a laminate as these steels are very corrosion resistant and tough.

Yes, it doesn't have the exact same alloy composition of either of them but is similar in class.

I'll give a look at VG2 specs, but IMHO I'd have liked VG10/SGPS clad a bunch more.
I don't like clads as a rule of thumb, starting from 420J2/ZDP goin' on thru 420J2/VG10 ending with this one (VG2/SGPS).
 
I don't see much reason to laminate VG-10 with SPGS that would be like laminating 440C with RWL34. Generally with laminates since they don't form the cutting edge you can focus more on toughness and corrosion resistance. I would prefer a 12C27M/S90V laminate. Of course you also have to pick the steels so you end up with the ability to harden them correctly under one austenization temperature.

I prefer VG10 over VG2/SGPS clad because I need strenght more than toughness for such a folder (P1).
How much HRC can safely reach 12C27?
