More on left/right hand setups.
Put the sheath in front of you on a table, with handle near you and blade tip 
far.
You can have your knife with spine on the right side as on the left one, for 
sheath is simmetrical.

For everyone: another plus included in the price is the Zirconium Nitride 
coating.
Sharpening: I found (EdgePro) that 24 per side on 320grit and slightly above 
with same grit microbevel are the best allround combo. Stock setting looks like 
being on the 28ish per side
Hint: when you receive your knife detach the handle and clean the tang with a 
soft cloth and some gun oil (Militech-1 will do or WD40). Wipe it clean and 
dry. Put handle on dishwasher upper tray, 55 degrees program. This will make 
you sure that any debris inside handle will go away, thus best contact between 
handle and tang will occur.

S30V:
This is NOT the universal all purpose hassle free stainless steel that is 
supposed to be. It delivers easier workability, slightly more toughness and 
corrosion resistance than S90V. End.
It was made to match requests for a CPM stainless steel cheaper to buy and 
easier to work than S90V.
I would NEVER buy a S30V based chopper knife, neither a survival one. CPM3V is 
far better to these extents.
Said that if we are looking for some serious cutter, well, S30V may just be the 
ticket if we don't wont to get into customs realm, but get ready to be 
disappointed if it stays on the 58-60HRC range (CRK). You won't notice nearly 
any difference in edge holding against a VG10 blade, unless your only cutting 
task is on Manila Rope. But, at such HRC, burrs when sharpening would be always 
behind the corner.
Should you be looking for a serious cutter you should consider S90V 
steel/ZDP189/S125V/10V/150V and a completely different blade profile. Not for 
Shrapnel.

Or you could buy a 61HRC S30V (Phil Wilson). Here you should be aware of 
getting a real cutter, with steel taken at its best (hardness/edge retention). 
Phil has posted his edge retention tests, make a search on Bladeforums.
Here we're talking about customs (and CRK are NOT), with cryo and triple 
tempering, as my Kevin Wilkins.
And here we're again:should S30V at61HRC deliver a quantum leap forward in edge 
holding, i.e. an edge lasting the double than N690Co at 61? Not at all. Then ?

S30V deserves cryo and triple tempering to give its best, as all of the CPM 
high alloyed steels. N690Co at 58-60 (Shrapnel) is more forgiving and more 
resilient than S30V@58-60 HRC. Edge will last slightly less, corr. resistance 
will be on par. Sharpening on the field will be far easier.

Last but not least: Kevin on his biggest folder uses N690Co 3.2mm thick. Should 
you opt for S30V it would be 4mm thick. Does this say something or not?
