Was tempted to custom order a Grip and just not sure I would really notice the difference between 154cm, n680, d2, and the s30v. In the descriptions of the steels they donMt really say anything that makes me go one way or another.

I did just get a Bone Collector but I have not used it enough to make an impression on the d2 steel.

Anyway what do you all think?

I tried doing a sea4ch but I couldn't find anyone else asking
 
D-2 D-2 is sometimes called a "semi-stainless". It has a fairly high chrome content (12%), but not high enough to classify it as stainless. It is more stain resistant than the carbon steels mentioned above, however. It has excellent edge holding, but may be a little less tough than some of the steels mentioned above. And it does not take a beautiful finish. Bob Dozier uses D-2

CPM S30V:
The newest stainless steel from Crucible, purpose-designed as a cutlery steel. This steel gives A2-class toughness and almost-S90V class wear resistance, at reasonable hardness (~59-60 Rc). This mix of attributes is making S30V one of the hottest stainless steels going, with makes such as Chris Reeve switching from BG-42 to S30V

D2
D2 is sometimes called a "semi-stainless". It has a fairly high chrome content (12%), but not high enough to classify it as stainless. It is more stain resistant than the carbon steels mentioned above, however. It has excellent wear resistance. D2 is much tougher than the premium stainless steels like ATS-34, but not as tough as many of the other non-stainless steels mentioned here. The combination of great wear resistance, almost-stainlessness, and good toughness make it a great choice for a number of knife styles. Bob Dozier is one maker who uses D2. Benchmade has begun using D2 in its Axis AFCK.

N690 is manufactured by Bohler (Bohler Uddeholm in Australia). Hard to get anywhere but Europe and sometimes in Austria. The specs, according to my source - 1.05% Carbon, 17% Chrome, 1.1% Molybdenum, 0.1% Vanadium, 1.5% Cobalt. very similar to 440c steel, but honestly more like vg10 from austria
 
In daily use,
  • I notice the difference between 154CM and S30V, with S30V holding an edge longer.
  • I notice the difference between S30V and D2, with D2 holding an edge longer.

I have a blade in N680, but have not yet really carried it.
 
I love the D2 on my BM710, holds an edge for ages, but I don't beat too hard on my blades. definitely better edge holding, if not toughness, than my BM741 in 154cm (which is definitely easier to sharpen, and I have beaten up up a fair deal..). So... they are both good steels, in my opinion (I won't compare them other manufacturers) for EDC, the D2 is a little more work, for me, just keep it oiled, clean, and know it will take longer to sharpen than many steels. I know D2 can be brittle, but I have not chipped mine yet, so far, both good. can't speak to the n690, yet:D
 
Thanks guys. Looks like I would go with the D2 if I do it. I just realized I misplaced my flashlight (Fenix 32) and headlamp. Going to be a spell till I have the funds to get that if I don't find the $140 in candlepower I lost
